The top-loading NES will play every American game and even PAL games (if you don't mind possible glitches caused by the format difference).
(well, at least every LICENSED game. As for unlicensed games, Tengen games should work (I've tried the one unlicensed Tengen game I have and it works), but I've heard others won't. Possibly because Tengen cloned the NES' lockout chip but the others tried to brute-force there way past the lockout, which no longer exists in the top-loader.)
Wait, when you said by amazon, are you sure if it's an OFFICIAL top-loader, or a clone?
Clones should play SMB2 just fine as well, but will have trouble with games with some chips (such as the Nintendo MMC5 chip, most notably used in Castlevania III)
