No, as long as it is not a mod and its your own idea it is not
It's legal as long as you don't sell them or give them out
To put it very simply, yes.
Only if you sell it.
No you don't need to divide to sell video games.
No its illegal only if you sell for a profit!
No. The games have age-ratings for a reason, though. If you are young and attempt to purchase a 18+ game, then the store may refuse to sell it to you. But no, it is not illegal to play them.
they sell dvd's and video games
They do not sell any games that work with both the Wii and PS3. You can mod your 360 to play Wii games but that is illegal and Microsoft will get really mad at you.
Blockbuster Video stores do often sell used video games such as Gamecube games however, they don't sell used Video game hardware such as the console itself.
