After playing Aleste 1 and 2 for the Game Gear, I've concluded that Compile shooters are awesome and that I must own as many of them as possible. To that end, I'm trying to list all of the company's shmups. Here's what I've got so far:
NES:
Gun Nac
Zanac
Half of The Guardian Legend
SMS:
Power Strike/Aleste
Power Strike/Aleste II
Sega Genesis:
M.U.S.H.A./Aleste
Game Gear:
GG Aleste
GG Aleste II
TurboGrafx/TurboDuo:
Blazing Lazers/Gunhed
Spriggan
Spriggan Mark II
SNES:
Space Megaforce/Super Aleste
Spriggan Powered (?)
Sega CD
Robo Aleste/Denim Aleste
PSX:
Zanac X Zanac (Anyone play this?)
Feel free to add to this, or to mention Compile's non-shooters, like Golvellius, Shadowrun, or even the accursed Puyo Puyo series.
