The PSP version is completely different to the others. It doesn't play as one ongoing level, with jumps, fights, bosses etc. Each level is often just one room, and so is extremely disappointing. I like the controls, I like the fact that Indy actually has his damn satchel, there is a little bit more to the story, but there's just not much to this game.
However, I do find it difficult to find some of the artifacts! The glory moves are quite difficult too! Don't make this your main version of the game, but it nicely backs up the Wii version.
As for exclusives, it's got a level set in 1922 instead of the Sudan (it could have easily had both and extended the game's lifespan by about 20%, but nothing about these games are generous). However, don't expect some glorious Young Indy return as some have. This one is just one room and makes little sense - I thought the Jade Sphere was in the Star of the Orient? It lasts just a few minutes, the time it takes to press three buttons.
As for other exclusives, apparently it's got some time trials based on the movies available once you've finished. Judging by the rest of the game, I don't expect much!
The PS2 version is a cut-down more-glitchy port of the Wii version. There's no co-op, no Fate of Atlantis, much less combat moves and no exclusive content. I'd avoid it if you can.
The Wii version is the "main" version, although that's not saying much. I must admit I'm now enjoying it, but it's incredibly short, the storyline is clearly missing cutscenes that were probably going to have been ported from the 360/PS3 versions and now simply aren't there, the level design is very claustrophobic with many stupid invisible walls, and there are several really frustrating moments. There's no easy mode either, which goes against the casual feel of the rest of the game.
However, the co-op mode I bet is really great. It may even have a story! I'll try and play it next time my sister comes round...
The DS version is the dark horse. According to people that have played it, it suffers less storyline gaps. This is presumably because it would never have handled the same PS3/360 cutscenes as the others, and so they made their own comic-book-style telling. Indy also has his satchel, yay.
There is an exclusive level set in the catacombs of Paris (don't know how that fits in the game, but whatever). However, I have no idea how it actually plays! If it plays like the Wii/PS2 version, it might be worth getting. If it plays like the PSP version, my advice about that version is the same.
Who here's actually got the DS version and can tell us about it?
