RPG's started that I haven't finished.....
Baldur's Gate I - I've started this game well over a dozen times and furthest I've made it is to the Nashkel(sp?) mines. After a friend of mine showed me the ending and since I've already completed Baldur's Gate II, my desire to finish this game has waned.
Neverwinter Nights - Like BG1, I've started this game over alot but just can't finish it because the story didn't draw me in and I can't get past the stupid radial menu and bland graphics.
Wizardry 8 - Great FPRPG which I'm about 1/2 way through but stopped playing because a majority of my PC time is playing WoW. I've known about this game for a while now but didn't start playing it until last year. Hopefully I'll get some time to finish this one, it's still on my HD.
Oblivion - This game overwhelmed me, who knows when and if I'll ever finish it. Plus, I love a game that's story driven - Oblivion's main story is about 20% of the game and the other 80% is side-quests.
Dragon Quest VIII - Love this game but turn based battles started getting boring and the grinding in this game isn't fun. I do eventually plan on finishing this one day.
Final Fantasy XII - Best FF game I've played so far and still playing it now. With work, family, and juggling my gaming time between WoW and FFXII, it's been a long process to complete.
