Free games I have? Hmm.
I tend to play a lot of Minecraft [Not-free] and Terraria [Also not-free, but cheaper], though I do have quite a few free games in my collection, both fangames and non-fangames.
- Non-fangames -
Cave Story - A story about an amnesiac robot who has a gun.
King Arthur's Gold - A multiplayer platformer battle game in the vein of TF2 and Terraria.
Legends of Yore - A retro RPG with fast gameplay.
Phantasy Star Online: Blue Burst - I play on the popular schthack server. I'm not sure if this is SUPPOSED to be free, but I've heard nothing against it.
Team Fortress 2 - It's like Call of Duty, but it's actually good and the community isn't made up of whiny 10 year olds. [It's made up of whiny 18 year olds instead. "ARGH Y CANT I OPEN CRATE"]
Wow, lots of my games I did actually pay for, thinking about it. You pay for quality, I guess.
- Fangames -
Psycho Waluigi - I have to say this off the bat, this is my favourite of them all. You control a psychic Waluigi in a quest to take over and rule this mysterious land. Yes, you're the bad guy.
Halo: Out With a Whimper - A pretty good 2D Sidescroller version of the Halo franchise, if I do say so myself.
Kirby Cosmic Chaos - A quite awesome 3D Kirby fangame, even if it is a demo. Just be sure to play the 2009 demo, not the petite 2010 one. Though the 2010 one IS pretty.
Megaman Battle Network: Chrono X - I was quite surprised at this one, actually. It feels like a real MegamanBN game, and it PLAYS like a real MegamanBN game. I'm surprised this wasn't made by Capcom.
Super Smash Flash 2 - Except for the addition of annoying anime characters, this game's quite fun.
