I loved TRA on the PS2 and couldn't wait to play it again (I still have the poster from the strategy guide of Lara fighting the lions). However, this version is definitely rough around the edges compared to the console versions from years ago, at least through the first area of the game. A lot of graphical glitches where Lara will continues shimmying in thin air instead of rounding a corner then teleporting over to where she's supposed to be, the camera being a little too stuttery, and the enemy AI sometimes just goes completely dumb. The first boss fight in the game is against the T-Rex and it kept getting caught in an animation loop where it wouldn't attack me unless I stood in a specific spot. It turned what's supposed to be a heart pounding fight between a woman with 2 guns and a dinosaur into something where all I had to do was mash the trigger as fast as possible. I still like the game and will play it to completion but the original console versions are better. For the introductory price of 98 cents it's can't miss right now at least.
This is my third time purchasing this game, and I'd do it again. I originally played both Enemy Unknown and Enemy Within on the Xbox 360 with this being my first time on PC. Both versions of the game are absolutely fantastic. It can be frustratingly hard but when everyhting "clicks" for you it becomes so fun. The base and resource management part of the game is deep enough to make you really put thought it your choices, but light enough to not be overbearin, while the combat portion forces you to think through every move you make and plan your movements and attacks several steps ahead. The story of the game is pretty light, aliens come down and you gotta stop em. There are a few FMV cutscenes talking about some broader themes like if the technology XCOM is obtaining from the aliens is too much power for humanity, etc but it's nothing too deep. The gameplay loop is what carries XCOM. As the description says this pack contains both the original Enemy Unknown and the expanded version of the game Enemy Within. The base game is great on its own and is worth a playthrough but Enemy Within does add a lot to the experience. You can jump straight into EU and not miss anything as it is the orignal game just with new features. I only have two real gripes with the game; soldier customization and discovering aliens in combat. The soldier customization is good but not too deep, even with the added options in Enemy Within. That being said it's still one of the most fun parts of the game. During battle if one of your units spots a group of aliens they get a free turn and can move into position, which I guess would be "realistic," but it can be really frustrating when you're trying to move your team up as a group. This forces you to move very slowly and deliberately if you're not trying to trigger new enemies. Other than those two things though, 5-star game.
