This version works better than the one on steam. The game can look quite beautiful at times, though it's quite a bit uglier than BS3, despite having better character models. The animation, in particular, clearly suffered in this game, and you can literally see the budget running out as you go through the game. There's quite a bit of inconsistency in the puzzles: some objects can only be interacted with after you've done some other, often unrelated tasks. This means that you never know if an object is just scenary or if it's interactible. It's a particular bad variety of pixel hunting. The story is enjoyable, even if we've seen similar plot points before. It's certainly worse than 1 and 3 and 5, but maybe better than 2?
The game has the worst controls of the trilogy, but has the best scenaries/level design... though it often feels like there's not much to do. The PC port looks quite a bit worse than the X360 version (which has decent motion blur), and even worse than the PS3 port (which lacks some effects from X360 version) - in the PC the hair shader is quite worse and there's no flashlight shadows. I'd still recommend a playthrough, just... keep your expectations in check. The PC version also doesn't have the X360's DLCs. The croft manor DLC is probably the best level in the LAU trilogy.
All the odd-numbered Broken Sword games are really good, and the even-numbered ones are kinda bad. But this one is the best. The beautiful 3D graphics are the nicest the series ever looked (even though the first one is also beautiful), though sometimes the polygons can show their rough edges. It certainly looks better than the second one, and the animation is much more fluid than in the 4th one. The puzzles mostly flow really well, and it's rare for something to leave me confounded. The story is also certainly exciting, even if it relies a little bit too much on coincidences. I have to say, I'm also a big fan of the controls. There's significantly less "pixel-hunting", and the direct controls make exploration feel less boring.
This game is almost a perfect iteration on the earlier Tomb Raiders. It has all the exploration and action you would expect from a game of this kind. The combat is less spectacular than Tomb Raider (no flips, as one would expect from Indy), but I find it more functional. The exploration is spot on, and Indy controls much more fluidly than Lara Croft in any of the Tomb Raider games. Unlike the later Tomb Raider games (like III and Chronicles), the puzzles here all make perfect sense. I actually had a disc based version of this game, but I couldn't get it to work with my 64bit Windows. Fortunately, the GOG version runs like a dream, and has perfect support for the X360 controller.
