I usually plug Lineage 2 free servers because it's a fun distraction for a week or 2.
But this time I'm promoting Maple Story... + hacks. The game is a mega boring ass grind fest, but it has so many fucking hacks. The best part is that the community consists mainly of 8-12 year olds who are too retarded to hack, so there still is a very small amount of hackers. Not only that, but if you botted overnight for a couple weeks, you could ebay your character for around $300-500. Not bad.
www.mapleglobal.com for the game.
www.m-secrets.com for the hax.
Unless you're against hacking or something...
