I dislike java, it's fat and sluggish!

But I was led to think that a grafic adventure (like, let's say... broken sword) would be a lot easyer then a card game (even more if the game is online).
I wouldn't have a lot of eye candy and stuff...
Anyway... I take this chance to remember I flunked math, and that I hate math with all my might. Apparently I must face it in order to get anywhere in programming, but exaclty what math-skills are required?
