I can only talk about the 2001 GBA game and the platformer that was made in conjunction with the movie as those two are the only ones I had played.
>Lego Bionicle (2001)
Isometric dungeon crawler, prequel to the entire series, navigation is a pain in the ass due to "pre-rendered" backgrounds, shooting at enemies is always a chore, mini-games are the best part of the game, entire thing can be completed in a couple hours, average game overall
>Bionicle (2003)
Summarizes the events of the entire series up to the end of The Mask of Light, 3D platformer, rushed through development, game is clunky in controls, short in length, remember it being fun but a few years since actually played it
As far as any of the other games, I have heard that Heroes like TT's other Lego games, except that it's a shooter.
