Heh. You guys have mentioned a lot of other things that I also do.

I'm very stingy with MP, causing me to use physical attacks far more than magic in most games.

In Fire Emblem games, I also stay away from the more costly weapons, usually just using whatever normal weapons the enemies drop (I almost never use the special effect weapons, since they count as rare items) and not buying any new weapons unless I have no choice, and then I usually pick up the iron weapons that last forever.

I'm a tightwad when it comes to cash in most games, treating it like I do most items. Unless there are shop-only items, I won't buy things from shops.

And, like JKTrix, I never use TMs in Pokemon games. Since HMs last forever, I don't mind using them, but I get other problems. Since Pokemon can only learn four moves I go absolutely insane trying to figure out which four I should give them. Another limitation problem, but of a slightly different type.
