To be perfectly honest, I didn't like Far Cry 1 at all. I thought the plot was silly, and the whole game was laughable. The game was massively annoying and unrealistic, and it pissed me off every step of the way. I figured that when I was in an intense battle that if I dove inside a barrack tent I could be safe for a bit, but no, apparently the enemy bullets can shoot through the tent (somewhat realistic) but they could still see me (exactly unrealistic), their accuracy was better (nonsensical) and I could not see them back (duh). Tents are freaking death traps. There were some parts that provided an enjoyable challenge, but for the most part I found the game to just be annoying, repetitive and plotless.
Crysis on the other hand I loved to death, especially Warhead. Crysis had this fantastic and "big" feel to it. The game was HUGE. I don't mean huge as in lengthy or expansive, but I mean the setting and the way you traveled through it - no corners were cut. I think by the third and fourth levels it did start to feel a little bit repetitive with the constant similar setting, but each of those four also had their great moments: 1) The introduction to Contact is epic, and the middle portion is fun as hell; 2) Recovery had a great tank fighting scene, especially when you camp out in the gas station and then blow it up; 3) The night portion and ending to Relic were mysterious and creepy, especially the part where you're driving a boat away from the helicopter that chases you downstream and when you fight the Korean Nanosoldiers; 4) It was so incredibly satisfying blowing everything up in Assault, especially the AAA's, Korean watchtowers, and of course that awesome scene where you bomb the watership with an airstrike. After that, Onslaught was freaking beastly, and every level that followed was a non-stop chain of plot twists and crazy level design that lead up to the number one most epic final two levels I have ever seen in a game to date. How is that? Well in Ascension you're flying a VTOL through the clouds, dodging tornadoes and mountains while fleeing an expanding sphere of ice. Then in Reckoning, you get to watch the island you spent the whole game on get nuked, and then you fight face-to-face a gigantic forty-foot quadrupedal beast-of-an-alien that you fire rockets and Gauss bullets at it while dodging its ice blasts and the various objects it throws at you - like that VTOL it grabs out of the sky and chucks at your face. THEN, IT ISN'T OVER. YOU GET TO TAKE DOWN A MOTHERSHIP WITH AN EFFING NUKE GUN FFS. Wow. And if that wasn't enough to melt your face, the final cutscene shows your entire aircraft carrier and the mothership getting sucked into a whirlpool, and then the ocean basically explodes. On another note, I really liked the aliens. They were creative and unique in my opinion, and I don't know why so many hate them. Their animations were detailed and very well done, probably some of the best I've seen in any game. On top of that, the glowing exosuits are slickly sweet.
In Warhead, there isn't a lot to say other than the fact that it's so, so, so, so, so, so, so, so, so, so, so damn fun. The entire game is basically a rollercoaster of action, varied gameplay and creative level design. Oh and did I mention the vehicle scenes? They were so well executed, and probably the best parts. Every single moment of this game was almost perfect, and I couldn't ask for anything more.... That is, except for the final level, which in my opinion was honestly one of the most uninteresting parts of the game. Sure there was fighting, lots and lots of fighting, but compared to the rest of the game it was nothing, and compared to the ending of Crysis 1, it was certainly nothing. It sort of built up the entire game consistently, through all six levels, before it came to an extremely exciting climax, and I couldn't believe my eyes during the cutscene with Psycho, the exploding train, Kim Sun, and the drowning Korean, but then it sort of rolled off at the end without much of an impact. But holy ****, that was one fun game that I could play a million times over.
Crysis 2 now I found to be a bit of a letdown, but not too much of a letdown. I'll start off with the good: The game feels detailed as hell and the atmosphere is amazing; it literally felt like I was inside apocalyptic New York, and the land I was standing on could crack apart at any moment. The weapons are great as well, and the story is suspenseful and edgy, something that really kept me on my feet. The length was also a smashing bonus, because it really had an amazingly satisfying and creative ending despite the lack of a final boss battle. It was definitely a memorable game, and when replayed, it's even more fun than the first time. Now the not-so-good: The game doesn't have that sane "big" feeling I previously mentioned Crysis had, but it does feel a lot bigger than other games such as Battlefield and CoD (now I know some people might say that Battlefield was a big game, but it to me honestly didn't cut the cake, and it felt rather average despite having larger landscapes). Crysis 2 also suffered from consolization - don't say it didn't, it did. I don't mean that as in limiting itself for console specifications, but I mean that it gave into what the common console gamer wants, which is meaty, ball-blazing action, and that's exactly what Crysis 2 was. Also, I know the second last level was trying to pay a tribute to Onslaught from Crysis 1, but the fact that you couldn't take the driver's seat kind of blew it.
So for me, it goes:
Crysis Warhead > Crysis > Crysis 2 > Far Cry
