I appreciate the comments and thoughts - nice to know I'm not alone on this! One question though - if I'm a commitment phobic, how do you explain 12 years of marriage?

I actually did complete WarioWare for the Wii (not shake it, the first one - party game), if one can complete a party game, and I also beat Bowser in Super Mario Galaxy....but by no means have I conquered every world in that game yet. From a computer side of things I actually finished Spider-Man 2, and I loved Syberia I (that things final cut scene still is emotionally off the chart for me).
I would agree with you all about how engrossed one is in the story. It also depends on whether or not I'm completing it by myself or not - Chad, in mentioning the Lego thing, brought back many horrors. I love my 7 year old kid to death, I really do, but when we play "Lego Indiana Jones", or "Lego Batman", what is her favorite thing to do? Come over and punch my character for no reason until I break apart, losing all my collected lego token things. Usually I can tolerate once, but by the 10th time, I get up and leave the room. I find I do much better when I can play alone - which isn't often anymore these days.
I never will forget this: one day we were playing LIJ, and we were in the temple of the Holy Grail where the saws come along that cut your character. I had to leave for a restroom break; when I came back, she had gotten mad at having to wait, and had pushed my character into a corner near the two saws so that every other pass my guy was getting chopped in half!
I also agree with the idea of having too many games and not knowing where to start....but again, I think part of my problem has been the loss of data. After many months of sitting here listening to you all talk about Resident Evil 4, I finally gave in and tried it out - and I fell head over heels for the thing. I had gotten Leon to the first really major place in the game (I assume near the end of part 1, cemetary looking place with monuments, etc), when the Wii bricked the second time and lost all that work - and you know how hard it is to get through those early villages (Level 1 part 2 or 3, I think, where there's nothing but a host of undead). I still have RE4 but haven't started back through it yet. Because of that, also picked up The Umbrella Chronicles, but can't get/ haven't gotten past the damned giant scorpion yet on the train.
The one game for the Wii - that for all it's psychosis things that fascinate me - that I can't seem to get into at all is "Silent Hill: Shattered Memories." I either suck at looking for stuff, or find it too freaky to go into the really scary parts...because I'm still just running around the town. I think I'll bank on a little too freaky...when I entered the dress shop and called for the daughter, heard the little voice laugh at me, I turned the sucker off (I was here alone at the time- was REALLY not ready for that).
