I am currently playing Anniversary and have played all the previous games several times. I switched to a game pad for Legend and I would now not go back to using the keyboard. I was anti gamepad for games like these, but I bought an X-Box wireless controller for windows and it’s excellent. No need to remap the keys at all and you can sit further away from the screen which is helpful.
With regard to Tomb Raider games in general, I enjoy them all. I’ve just finished TR1 with Glidos and the texture packs from the Glidos website – it was great. Works on Vista no problem. No I’m playing Anniversary; I’m please to see that it’s more than just a rewrite of TR1 but is very similar. I’m looking forward to Underworld when I’ve finished Anniversary. MY favourite is TR2 and the Venice level is the best.
