all games are not created equal

Frankly, I suck at Dr Mario.  My girlfriend loves it, her entire family loves it, my family loves it, I hate it.  I cannot see for the life of me how everyone is able to comprehend the combos and such that they build to win vs matches.  Maybe it's cause I'm color blind, but I doubt it because I can clearly see between yellow, red and blue (thank you Nintendo for sticking to primary colors)

Tetris, on the other hand, I rock at.  Just give me black on a nice amber background and I'll get you past level 15 no problem.  Play me and vs and good luck.

I think the concept of tetris is more accessible than Dr Mario as well.  Though I remember first playing when I was very young, I didn't know what I was doing so I just tried to make blocks fit all nice and snug.  Then I got upset when I made a line and they disappeared cause I worked very hard on making them fit nicely.  Oh well.

Also, who can forget the catchy Tetris type a theme?

these games are both classics. but Dr. Mario takes the cake. its a fun, simple puzzle game with catchy music. and mutliplayer was always fun.

you don't take turns, you play against each other, through time and through skill, a race to see who can finish and who will fail.

in Super Mario Bros. on multiplayer you take turns, waiting for your competitor to die. >.> or making them die via messing with them in fun ways.
