My current favorites are:
- R6: Raven Shield - Great modern indoors/close range game. People complain about the AI but really this game is all about multiplayer... Weapons and stuff feel real great. No bunny hopping lamers or similar crap like in CS or something... Very tactical feel at least if you're playing with a good group of guys online. This is the game to get for indoors "tactical" FPS gaming
- Medal of Honor: Allied Assault and the expansion MOH: Spearhead - Great WWII game. Fun singleplayer, but multiplayer is it's heart as well. If you play on servers with a realism mod to up weapon damage and loadouts to more realistic settings etc it is a
great game. The non-realism mod stock game annoyed me though... (plenty of realism servers online, I play on nothing else) Personally I prefer this over BF1942 due to superior multiplayer IMO (smaller scale, no vehicles but all I'm after in these games is infantry combat anyway... BF1942s largely arcade feeling and poor netcode last time I ventured a go at it pissed me off. Everyone's too busy d*cking around crashing the crappy vehicles and such... Weapons didn't feel powerful enough, etc {may have been addressed in patches, not sure})
- Infiltration - Free realistic tactical shooter mod for the Unreal Tourney engine. Lots of fun, mainly made for online gaming, newest version is supposed to be coming out any time now:
http://infiltration.sentrystudios.net/ Has no crosshair and a type of iron sight aiming/shouldering your weapon implemented (FOV is too far away from the sites due to UT engine constraints, but hey...) Your hands have some free movement on screen before your view/head moves unlike regular FPSs. Takes a little getting used to but I really like it.
- Operation Flashpoint - This is the game to get if large scale outdoors combat is what you're after. It's mainly a single-player game as the online setup is frankly subpar IMO. You have to use gamespy, can't join games in progress, lag is often a problem, etc. But the vehicles that require multiple people to operate and the large maps add alot if you have the patience. The few times I've been in a good server with a group of good players it was some serious fun. The game is a little less polished than some, and is a little clumbsy at times, but it is offset by the huge battlefields/environments. OpFlash Has several expansions (in the original you are US troops in a conflict, in Red Hammer you are on the Russian side, etc), I especially enjoyed Resistance, which pits you as a major part of a rebel uprising against Commie forces in a island nation. Goes from you with your shotgun to commandering Commie arms and equipment (including tanks and such), performing ambushes on convoys/patrols, sabotaging their equipment, etc. I thought Resistance was one of the best singleplayer games I've played in a long long time (of course I really liked the theme/story of it to begin with...)
- America's Army - This one I'm kinda torn on. It's a good engine (UT2k3 based) and has good weapons models and maps, and of course it's a free download. But something about it turns me off to it. Seems like the weapon damage is pretty weak alot of times, that or the netcode is such that it's laggy without appearing so. I'll often dump into an enemy at fairly close range and we'll both sit there blazing off a mag at each other, each taking several hits. It takes more hits than I feel it should most of the time, kinda ruins it for me... That just doesn't feel "tactical", most of the time I'd rather play Raven Shield where I put a quick burst into a target and assuming I did my part aiming and controling movement so I don't miss they go down hardcore. Of course Raven Shield doesn't have the outdoors maps like AA does. I do love the iron sight aiming in AA though, I wish more games would go to that and do away with a cheesy crosshair and no-shouldering your weapon function. I keep hoping one of these updates they'll up the weapon damage values in AA, maybe they have since I last played... Someone let me know if they've addressed that or if I'm just crazy about that part to begin with...
I'll mention that DF: Blackhawk Down is alot better than the last couple Delta Force games IMO. The singleplayer still leaves something to be desired, and the multiplayer is hampered by the DF series patented crappy netcode/lag, but it is still fun (mainly for multiplayer, single gets boring fairly quick). Not quite as realistic as could be. There is still something to be said for the bigass boards, good landscape, and fun to use weapons. Nothing quite like getting on a (Mk 19?) automatic grenade launcher and smackin some suckers in a big Somalian town that looks/feels the part. I enjoy the miniguns on the blackhawks and Ma Dueces on the Humvees too (vehicles aren't driveable, but cruise on set paths in the multiplayer maps where you can man the guns)
Splinter Cell isn't a FPS, but it's fun as a stealth aimed game in 3rd person. All singleplayer, lots of fun little challenges. I personally wish you could be more free with the firearms at times.
