Tomb Raider 1 - Remade on todays machines with greater movement for Lara like Prince of Persia and better enemy A.I. They could incoporate some of the innovations from the later games like vehicles, but it was the level design/puzzles that were great. When Paul Douglas left the team, they lost the decent levels - Midas, Cistern, Lost World, etc.
I want Lara to be Tomb Raiding, with a bit of DaVinci Code like revelation.
