Robbeasy: Morrowind , using Morrowind overhaul. Never really got far into the game, seeing if it proper grabs me this time..
For light relief ive got Shadow Warrior, and Flatout Ultimate Carnage. Oh, and Race Driver Grid is also on here.
And I've got Blade of Darkness to finish as well. And Anvil of Dawn is loaded up too.
Of course Dungeon Crawl Stone Soup is always on my HD, along with Super Hexagon....and, for playing with my 5 year old, there's Peggle and Angry Birds Space....
Praps I should concentrate on one thing at once.....;)
If you own Oblivion as well, there is the Morrowblivion project. That's what I used to play through the game. I owned Morrowind when the game first came out, but my roommate played it a lot more than I did because I didn't have the time to devote to a deep RPG. Then a Morrowind playthough just took a backseat to other games for years. I highly recommend the Morrowblivion experience if you haven't tried it yet. Much better than the Graphics Extender for Vanilla.
