wrong listing's

i'm starting this topic for though's that see flaw's, and error's in nintendo entertainment system's, and it's game's online info. 1 flaw i notaced at several site's is for cyberstadium basewars release date. here at gamespot, and several other site's are claiming it was released in 1991. when in fact, the copyright on the back of the box for the rev-a version i have, say's it's from 1990.

That's,probably when the trade mark was,filed
