I just would rather compete in something that isn't Halo or League of Legends seeing as I'm more interested in role-playing games and simulators.
Are there competitive leagues for RPGs? Usually it needs to be multiplayer.
Well, strictly speaking, there's speed-running. It's not competitive in the sense of LoL, Dota 2, or SC2, but it's as close as you'll get with a single-player game I'm afraid. Some of the best speed-runners on Twitch can pull in 4-5k viewers, which apparently pays decently.
Oh neat.
SRL (run by some of the SDA community) is a good place to start if you're interested in starting speedrunning.
I know I'm really great at challenge runs for action games (even though they're my least favourite genre. go figure) but I've definitely never had any experience with speed runs. Thats a whole different ball game I'm sure.
If you're interested, my favourite game to watch is Ocarina of Time. There's a good chance you've played it (without speed running it), so the incredible number of positively
insane glitches used in speedrunning will be appropriately dazzling. The 'any% run', meaning getting to the game credits, takes ~20 minutes. The 100% run takes a little longer but is still finished in a single sitting, and has a highly-competitive world record that was beaten less than a month ago.
On-topic: Armed with a friendly crew that had handled several missions together, I took us to a bank full of valuable safe deposit boxes. Our stealth attempt failed, but we broke into the vault with few problems. Two of the crew started opening boxes while two others covered the exit.
"Well, we've got enough cash, and the assault wave is over. Should we run for it?"
"...nah. This is the part of the mission that makes us money. Let's grab as much as we can!"
And so we finished off
another complete assault wave, opening more than half the deposit boxes in the vault with nothing but slow-paced lockpicking. Significantly, we held off the wave with only two people gunning while the rest opened boxes. It took a while, but man, did we ever get a good haul from that robbery!
