darkness said: If you have a 360, I’d suggest investing in one of those newfangled games that just came out (and with Black Friday, they may be discounted). I’ve really never heard of a decent free FPS game (was TF2 made free to play recently? I don’t remember, some game became free). Battlefield 3, Modern Warfare 3 and Halo: CEA all look like viable choices. Being a Halo fanboy, I’d recommend the last one, since the graphics are beautiful (the other two have gritty, urban, wartime environments, which are nice in their own respects), the gameplay is exactly the same as the old Halo: CE (with skulls and terminals, so that may shake things up), and the map pack it comes with is nice, since it contains remakes of Halo and Halo 2 maps as well as a firefight map with AI allies (betrayal!).
No 360. I got a Wii few years ago. Now that I look back, I wish I had gotten a 360. I just use my Wii to stream Netflix 
Arladerus said: TF2 is free. Fallout New Vegas is a great game to go if you like some RPG with your FPS. L4D2 was like $7 a few weeks ago, and $5 during the summer sale.
Yeah, TF2 is looking like my best option at the moment. The only problem I have with it is that it’s such a massive game, and each patch is like, 200~300MB.
