Does anyone know of any games (PD or commericial) that are like tetris
but expand upon the idea? I'm not talking Weltris, I mean a game similar
to the arcade tetris with added features (like added blocks and lines,
two-player simultaneous, etc).  Being a huge fan of tetris, I've been looking
for a better version of it for a while without success.

	Also, does anyone know if there was such a game, would it be a
copyright infringement? Even if the game was based on the same idea but greatly
expanded and changed?  Since 9 out of 10 games released are ripoffs of older
games (like defender, space invaders) it would hardly be an exception.  The
only case of copyright infringement I've heard of was between Atari (who owned
the home rights to Pac-man) and some other company (I think Oddessy 2 for 
their KC Munchken), but their are probably a number of others. 

Any thoughts on this would be greatly appreciated (its been burning a hole
in my mind for days now).
