Make an offline league server.

I don't see the particularly negative effect from unofficial servers. You wish to use them, they're there, if not, they shouldn't impact your game in any way. That's beside the fact that "offline servers" was an incorrect way to say it by OP; No actual networking capabilities have to be created for this.

As far as exploits and hacks, I can see some definite issues when implemented. However, after some scrubbing, the mode should stabilize, as the mode has far fewer variables on hand. There are more issues when new champions are added, and I don't think many want to see that flow to stop, regardless of the huge amount of champions already available.

Any such mode would be limited on its capabilities, such as only bot mode matches without IP/RP capabilities, and possibly without any skin/champion integration (although I'd hardly consider it a threat to game interests to allow the full champion pool while offline... You can only play against bots anyway.)

There are a few reasons why I'd REALLY REALLY like unofficial servers to appear. I'm going to use Maplestory's unofficials (they have tons) as an example.

1. Unofficial servers would allow crackers and programmers to unite and make game modes and champions and skins and all that that rito couldn't, wouldn't, or should not for legal purposes. In maplestory this occurred as people making entirely new classes, better graphics for the attacks of certain classes, and the super-common "returning your character to level 1 while retaining one high-level ability".

2. Testing purposes. Yes, exploits and hacks would be easier to find with all the game information you're open to, but in Maplestory, people used the private servers to find out how certain character setups would develop, in the order you developed them, and what would be the absolute best way to make a character with the highest stats, usually exploiting old game mechanics like intelligence gaining higher mana per level up, and then transferring mana to HP with scrolls. They even found out ways of predicting how well armor would protect you in the game, since that information was never released. Also, people could test skins before buying them.

3. No permanence. Without ranked, and without anything official to show the world, people won't stick with private servers for extended periods of time without going back UNLESS...

4. The possibility of a private server doing Riot's job better. It has happened before that a Maplestory ps had done PvP or some other game that Maplestory itself didn't add to the game yet, and soon enough pvp was added to the original Maplestory game. It was glorious! If a private server outperforms riot, it would be a beautiful sight, and riot's hurt pride would force them to either attack the private server or have to gasp compete. Riot would never allow itself to be beaten by a completely free service. A little competition would really shape up Riot's lazy attitude.

5. They can only legally run off of donations. The cash shops in Maplestory pservers were always based on money you could get in-game or as a reward for showing your support by posting on the forums or voting on that pserver on a pserver list. If they ever run for money they'd be taken down by force, though at riot's speed it'd probably be a few months before they do anything about it.

So yeah, mostly out of spite, but I think unofficial servers would be a really good for the players and for riot. They could even hire a scout to look for neat things on all the servers out there and copy them, sort of like what they did with jungle timers.

That's a red herring. Invalid. You have no idea if that's what would happen.

I'm pretty sure the op is asking for something like how Minecraft creates an instance of a server on your computer, then connects to it to play a single player game.

Even if it could be hacked, it makes no difference, as soon as you hop online, Riot could run a hash check to make sure all the data is the same on your client.

Couldn't be said better. I've played a game with both those issues from having data client side. I know what happens all too well- It's not good.

You don't need a server for offline purposes, since you know, it's counter intuitive.

Sorry, not really technical here with using the term "server" so forgive me. My whole point is I want to play league offline with bots when I don't have internet, without having to sign in.

That's not what he's talking about. He wants to play bots offline. Which would be easy to implement.

well then you wouldn't have to do it.
some people play league just to pass time. I have several friends in the military who are deployed with a laptop, but don't have internet access all the time who would absolutely love the option to relax in the evening with a few bot games. Just because something is boring to you, doesn't mean it's not a good idea.

Dont get me wrong, having some way to play this game offline. i just dont see how it would be possible. First off more than likely it would need a different client, server, basically making a whole new game. Even with that how would IP/Leveling Up/Etc work? Im sure someone would make programs to "cheat" to make so you can get IP faster. Again i would like this idea, just seems like more work/problems than actually doing any good for the game!

Start at level 30, everything unlocked. No need for IP or leveling up. Even if that's not how they did it, would it matter if someone cheated it? It's an offline version. It's like playing Skyrim. No one can see what you do. No one cares what you do. It's an offline game, even though it's downloaded from the internet.

Limited IP gains on this "server". I'm talking like 10-20 per game. Leveling up can work the same IMO because theoretically you could level all the way up to 30 playing only against bots, the IP reduction would just be to prevent IP gain spamming or whatever you want to call it.

as I said in a previous comment, I have several friends who are in the military and deployed, who still have a laptop for when they DO get internet - but don't have access to it all the time.. Those guys have said a thousand times how much they wish they had something better to do offline, and a bot game of league without ragers or trolls for them to relax with while they are miles away from home I think would be kinda cool. Sorry that you didn't think about anybody but yourself.

I'm 90% sure the bot AI is handled serverside, and probably a fair chunk of other stuff too. A lot of that would require code rewrites. Not necessarily really hard ones but... it's a pretty big undertaking. I think you'll have better luck finding something else to play single player.

Writing AI is the hardest and most expensive thing in game development.

wtf are you even saying. is there an English version of the nonsense you just typed? This post wasn't even made by a person that works for riot.... so how you think it's "riot's way of gauging blah blah" you're an idiot. This post also said zero things about this being a monthly fee.... you're seriously confused. somehow.
