E.S.
My 2 older ones (8 & 6) have summer birthdays 3 weeks apart, so like you we got tired of smaller presents that clutter up their rooms. We ended up buying a Wii system for their birthdays. The Wii sports games are great for even little kids because they just have to move their arms (my 3 yr old now likes to bowl, even though he keeps "throwing" it into the people behind him). My kids enjoy playing these games together and I have to admit I'm getting addicted, too. We have a family contest every so often to see who can get the highest golf score or who can win at Mario Kart. I also like it because you have to move to do most games on it.
