I'm a FPS fan...big time. I've played them all since Wolf 3d. I started online multiplayer FPS gaming with Quake 3 Arena obsessing over the fast paced death match insane combat. I find that I hate many of the most popular FPS like Unreal Tournament, Halo series, and even Counter Strike. So I played Q3 hardcore for years until I discovered Return to Castle Wolfenstien for the original Xbox and was absolutely blown away...the teams were class based with various classes like soldier, engineer, and medic and it made the game play so deep and rich.
I kind of quit playing FPS outside of Half Life 2 death match for years due to just being bored with the genre...then came Team Fortress 2. I actually picked up the Orange Box for the Xbox 360 and played all of the other 4 titles before even thinking about picking up TF2. When I finally did, I was awestruck.
Perfect balance, humor, graphics, sound design, maps, and most of all, game play.
Eventually the crappy lag of P2P XBL and the very few players in the community pushed me to RE-buy the game on steam PC and I've been playing like a freaking idiot for months since.
Every class (all 9 of them) is like learning a whole new FPS. It's got that something that 99.9% of games just don't have...soul. It is incredibly fun and addictive and if you find the right group of folks to play with you it is a completely unmatched experience.

After Valve released the Team Fortress 2 source code, developers and modders are reviving TF2 VR, making it bigger and better than ever.
Seems dumb, multiplayer fast paced VR... Sounds like a recipe for disaster.
Source 2 versions of the games they had, remakes or sequels to their games should've come out like a decade ago, now they'd need a heavily upgraded Source 2 or just Source 3 to be up to par with current engines tbh..

Valve: "Mod makers, rejoice! We've just released a massive update to the Source SDK, adding all the Team Fortress 2 client and server game code. This update will allow content creators to build completely new games based on TF2. We're also doing a big update to all our multiplayer back-catalogue Source engine titles (TF2, DoD:S, HL2:DM, CS:S, and HLDM:S), adding 64-bit binary support, a scalable HUD/UI, prediction fixes, and a lot of other improvements!"

Behind the aimbots that have plagued Team Fortress 2, a far more sinister story of harassment has unfolded - and it's only getting worse.
