I had the same situation, except I had an allowance of roughly $3 a week, and only if I did all my chores for the week. Also, we never got a game for end of the school year or anything like that. If I wanted money, I'd ask for extra work from my parents, or from my grandparents.
Tell your parents you want to buy some stuff, but you need money which you can't get, but that you'd be willing to work for them for the extra cash. For example, sometimes we could clean all the bottles that my dad has in his collection (old coke bottles and stuff, they're pretty cool). If they won't do that, there isn't much you can do.
Also, you have $35. That is enough for a used game, you just have to find what you want used a year after release.
