Dumb Raider : Die 4 times in the first 15 minutes of the tutorial.

It was a good surprise : I don't know why, but I was convinced that Tomb Raider Legend/Anniversary/Underworld were PS2 games. Not at all ! It's really a beautiful game.
Edit : Actually they were PS2 games, but Underworld was on PS3 too.

Thank you again ! Here some news.

After I won TR Underworld and started to play, a friend of mine, who is a really huge fan of Lara Croft, was jealous. She wanted to play the saga again (she had it on PS2). So I bought Legend-Anniversary-Underworld for her (I'm such a generous potatoe), and Legend-Anniversary for me (thanks to the bundles, it's worth almost nothing, ~80cts per game).
We've completed Legend two days ago, now we are in the middle of Anniversary. Then finally I'll be able to play Underworld with her, plus another friend who haven't played Underworld yet (but beat Legend+Anniversary a few years ago).

So, to put it in a nutshell, thank you again <3
To win a game feels good, to play it with friends feels better (even if I paid the games for them <.< )
