I hate Myst. It's probably not true, but I think it brought about the end of the adventure game era. There are far better adventure games than Myst.
This, friends, comes from someone utterly clueless. Myst is a classic that defined the adventure game genre. Everyone should play it once, though I'd always go for a PC version over the inferior ports.
Go to Gamestop, buy a Steam card, and use it to purchase Ys Origin. You won't be disappointed. For more info: http://www.worldofys.com/yso/
