If you get a chance, download and try "Forge". It is free this weekend (April 26, 27, 28). Forge is a fantasy-style third-person shooter. Someone described it as "fantasy TF2", which is fairly accurate. I played it for about 20-30 minutes the other day and it was fun, but will take some getting used to. There are five classes to choose from and a few game modes similar to TF2, like deathmatch, capture the flag, and capture point. It has a really nice general tutorial and even class-specific tutorials, plus a bot arena that lets you practice the class after you learn them.

Aside from the free weekend, it is on sale for $5 until Wednesday, May 1. I will probably play some more this weekend and if it turns out to be somewhat fun, I'll drop $5 on it.
