Best thing to do to make sure you enjoy playing the instrument is to take it to your local guitar shop for a setup. If it's not set up well it takes much more pressure to fret the notes cleanly and it can be painful both on your finger tips and the muscles in your hand.
Get a setup so its comfortable to play and you'll be able to play much longer.
Duuuuuude. This is a blast from the past. I had a Pizza Hut PS1 cd with a bunch of demos on it and Sled Storm was one of them. It has such a great physics feel for back then. I loved that game.
