RPGs can be a problem for me because I feel the need to do EVERY SINGLE QUEST which is probably why I never finished Oblivion. Right around dungeon/cave 80 or 90 you tend to start to lose interest.
Interesting, because Oblivion is one I may never finish, but I still play regularly. The ability to mod it in nearly every aspect keeps me replaying without finishing. The main quest has been pretty uninteresting to me since day one. But I really enjoy playing, modding, adjusting, modding some more, crashing, starting over, etc.
I finished 7 games in January, 12 if you count the ones I had finished before. Just man up and do it, it's not brain surgery.
Oh, yeah, you're right. I forgot to "man up" when I was playing those. Silly me.
