Co-op!?
BUT... one of the appeals of playing Tomb Raider was that you were 'alone' with Lara. (It's 2010, it's now alright to admit if you have amorous feelings for animated game characters). Do I really want someone else in the ruins with me watching as I try to run her into a corner or make her fall off a ledge to hear her neck crack?
The appeal of the game in TR4 (which is probably the last game that did really well) was that it had its own niche, a lot of the game concentrated on puzzles and story. TR5 onwards, they got confused. Did they want to make it an RPG? TR Underworld wasn't bad, though, they did regain SOME lost ground, but not all of it and the damage has already been done.
And as you, benevolent author of article, have noticed, it's just too easy. I'm guessing that the difficulty levels are so that they can attract the noob gamers as well and thereby maximize profit. I can't recall many instances in TR5+ where I got 'stuck' anywhere, they make things so obvious, they might as well have sold an animated non-interactive video of the final clip.
That all said, being a loyal fan, I will still pay to get shafted on this deal. Will it be on Steam?
