Any good FPSs out there

Operation Flashpoint was an excellent game. One of my favorites. Very realistic and the squad based missions are a blast. The mission editor is very comprehensive and specific (even better if you understand scripting), and there are alot of easy to install mods out there for said editor. Get the expansion packs too, though they might all be bundled together now for the game is quite old. I played ArmA some, not as much as operation flashpoint, but I would start at the beginning.

I don't particularly care for the Tom Clancy series. The enemies aim was too good (though the last one I played was quite old). The micro-management of your team and the plotting of courses of your team and perhaps other teams was also slightly over my head. I guess I just wanted a shoot-em-up and not all the planning. Perhaps another look is in order though.

Except for some missions that require a sniper, Rainbow Six doesn't require pre-stage planning. It's just there to your AI teams waypoints. I usually either A) don't bother with them at all and just go in with a single squad armed with silenced weapons, or B) use the pre-defined plan.

Day of Defeat: Source. It's something like 8 euros, and it's ******* amazing. I play it since 2006 and I never get bored of it.

In an older version of Rainbow Six I let a second squad go on their own, got a message of some sort, and they all got killed, all for in a row. They same thing happened to me and my squad not too long after. I don't really understand the best ways to move around those buildings and clear rooms. Funny thing, in that screen where it lists potential team members to join your squads, after about 2 levels they were all KIA. I soon gave up, though it still did evoke a chuckle!

The friendly AI is pretty hit or miss. More often than not, it's miss. This is especially true if you use non-silenced weapons, as virtually everyone on the map will be alerted. It takes only one tango you didn't see behind you to wipe your entire team. One way of making sure they don't die is to have them camp in a dead end or a well-used hallway. If they are on the move, their accuracy and reaction time drops significantly.

I thought the enemy AI didn't move. So a camping team would do nothing more than stand there, hence, why use that team in the first place? I don't remember what type of weapon they were using, I thought they were silenced. It seemed the friendly AI team would move into a room without a flashbang and without peeking around a corner, and one by one get picked off. I and my team play that way too! :)

Enemy AI moves, especially when alerted to movement sounds (hence why I use light armor and not heavy) and gunfire.

If realism is your thing, try SWAT 4. You can take a look at Spoony's hilarious Let's Play videos to see how it differs from Rainbow Six.

I'll check out that link later. You mentioned that you play ArmA, is that game just harder than operation flashpoint. I played one mission where you have to defend a base and all the men on my side run around like chickens with their heads cut off, they don't return fire, and quickly get killed. I continue the defense, the enemy goes quiet, I get no mission updates (the mission description is that you have to drive someone somewhere yet at the start you defened a base...?), then out of nowhere I get hit by some 'invisible sniper'. I stopped playing after that. Also, there seems to be too many one-man special ops missions and I prefer the squad-based ones. I'd try ArmA again, but something keeps me from doing that.

The original Operation Flashpoint was one of the most realistic, moddable FPS of all time.

The game came included with a programmer-level mission editor, and through the community you can find models for almost any vehicle or weapon.
However, the graphics and gameplay are terribly dated.

Operation Flashpoint: Dragon Rising updated the graphics, physics and gameplay, but as far as I know, is not very moddable and basically is just another 'me-too' realistic military shooter.

I've never played the Arma games, I've heard very mixed things about them. A lot of my old OpFlash friends seem to prefer outdated OpFlash to the Arma titles.
I keep meaning to grab ArmA2 from EB, but they won't budge from the $50 pricetag.. :(

Stalker has really gone crazy on me.

I installed it, got the complete 2009 mod working with realistic weapons. Since it was my first time, I went on Novice. At first the game was being crazy graphic wise, it seems that this computer hated the lighting options, so i put them on static and now no problems at all.

Anyway, got past the guy, up to where the bandits at the house, doing the mission. You had the option of using the help or going in alone. Since it was on Novice, I thought "I should be able to do this alone", sneaked up to the house and ended up in a firefight. All my shots either missed or do no damage, I was finding this weird. So I ended up running right up to one of the guys, close and personal style but I seemed to have died in a couple of shots.

Then tried the game again, now for whatever reason, the guy at the beginning doesn't talk to me at all, and no option to talk to him.

(re-installed and it is still the case. Looks like I just have to remove the entire game now)

Damn game. >_>

OPF looks terrific, textures aren't sharp and plants are sprites but when it all comes together it's almost photorealistic. Like Thief it has this distinct look that grows on you, when you consider the scope of the game you just got to admire the looks.
