If you're into First Person Shooter games, Team Fortress 2 is great. Huge player base, despite them all being a bunch of assholes, tons of cosmetics and weapons, which you'll probably never get since the player base make them more expensive than a wedding ring. Everything in the game is all side-grades, except stupid stuff like the Force of Nature, and pretty much eery weapon there. More experienced players have way cooler looking hats, and way better weapons so they're gonna kick your ass and make you cry yourself to sleep.
