1) more Xtreme-sport type rides (skateboards *with the ability to lie on your back while riding it*, wakeboards attached to boats, surfboards; snowboards, skis, and snowmobiles??? And maybe they could do small side-missions concerning some of them.) That would probably attract more buyers above all.
2) more schools (like a military academy or SWAT training)
3) the ability to do flips, spins, and fly faster on a Jetpack.
4) gas skateboards? skateboards with nitrous? ability to do tricks and flips on skateboards?
Hope u like those ideas. But if you ask me, I disagree with the Create a Character idea.
