SIB Tomb raider collection

If you like the new one i would recommend not to play the older ones, as they are actually good action/puzzle/platformers and the new one is just shitty quick time even based cover shooter. (so i heared)

The newest title is, from what I've heard, better than the previous 3. Underworld, Anniversary and Legend are all good. Angel of Darkness is highly flawed but even so you might like it for what it offers. The older titles are superb but keep in mind that the combat is outdated and so are the graphics, though they can still manage to be very atmospheric. Exploration and challenge are their strong point. In those two they are far better than the newer games. I would also recommend Guardian of Light, it is quite different from the others and NOT included in the bundle.

This and this are great resources for all things Tomb Raider. Also keep in mind that there have been expansion packs for 1, 2, 3 and an extra level for 4 but I don't remember if there is any "legal" way to get them these days. Also, I'm not 100% sure but the console version of TR1 (the old one) may be better than the PC version, so you might want to get that one and run it on an emulator.
