Resistance: Fall of Man has no real competition on the PS3 at the moment, so at this stage it's my favorite FPS title
Graphics
Overall, the graphics in Resistance are decent, they remind me strongly of Half Life 2 and also seem to borrow some style from COD and other war-time titles. Textures generally look nice from a distance, but there are certainly some shortcomings when you have a closer look. Many of the environments look a little bit rushed, with the majority of all 'ground/floor' textures often looking rough, repetitive and unoriginal. Lighting is well thought out, and the torch does come in handy here and there, though not to the extent seen in Doom 3.
Anti-aliasing is as discouraging as seen in a number of other (current generation) PS3 games. I won't be impressed if games still have the dreaded 'jaggies' in a years time. In fact, I'll be moving back to PC games if the overall game quality isn't keeping up with PC platform games.
Audio
I'm not an audio buff, but I found all of the sound effects pretty good, and the score to be equally decent. I have to say that the game didn't have the same suspense or intensity that I've had before with FPS titles such as HL2 or even GoW.
Storyline
Again, the title does feel quite rushed and the storyline is a little lacking, with only snippets of information provided at the end/beginning of each level, and not much by way of cut scenes/climax while in play.
Gameplay
I enjoyed much of the game play, although, it isn't as dynamic or unique as GoW but you can duck and 'dodge' much of the gun fire while in play - which in some respects is quite unrealistic, but helps to give players a fighting chance.
Weapons
The stand-out feature of the game is probably the nice range of very unique weapons, that make good use of the processing power available on the PS3 cell system. It has to be seen to be believed, but these weapons are 'smart' and deadly.
Other points:
AI is decent, but I found the difficulty scales from being quite easy through the first few hours of play and becomes much more difficult as larger groups of enemies are all trying to blast away at you - it's all a bit disappointing. The truth is, they haven't made it harder by making the enemies more intelligent, but just added more enemies to kill. I haven't yet seen an enemy try to shoot a barrel to blow me up or interact with the environment to cause my character harm.
