InfraSuperman: I recommend ePSXe. It's a great emulator, and ever since they implemented the HLE BIOS support, you don't even need a Playstation BIOS file for a lot of games anymore (they can't distribute that with the emulator, so you'd usually have to get it through... shadier channels or copy it yourself from an actual Playstation).
It's only for PS1 games, though, so Dog's Life won't work with it.
Cool stuff thanks, I'll make a note of it. A pity about Dog's Life, but I don't imagine that would entertain more than an hour :P In any event there are several PS1 games that I would've also like to check out, like Metal Gear Solid and Syphon Filter.
Asbeau: Vagrant Story
Morrowind
Diablo 2
Baldurs Gate 2
and the first 3 months of World Of Warcraft
I know many will not agree with my fifth choice, but it was so much fun for me when everything was new
No arguments from me :) Exploring Elwynn Forests for the first time is one of my fondest gaming memories.
