So, I'm going to be playing pretty much every shooter on the SNES, starting with Gradius III, and once I stop being a nub I'll post some gameplay on Youtube.

What To Look Forward To

Gradius III (classic shootyness. great powerup system)
Parodius (hilarious and light-hearted but still unforgiving re-tool of Gradius III)
Pop n' Twinbee (traumatisingly cute vertical shooter. will give a terrible phobia of pineapples and fish)
R-Type III (my personal favourite)
Super R-Type (not exactly my personal favourite >_>
Darius Twin
Darius Force
Imperium (an obscure vertical shooter, very similar to the arcade DonPachi! and MUSHA on the Genesis)
Rendering Ranger R2 (probably the most obscure shmup ever. alternates between contra-style run-and-gun and Darius-esque horizontal shooting. pre-rendered graphics)
Super Aleste (fun and decently-challenging vertical shooter)
Axelay (another of my personal favourites. uses lots of Mode-7)
Thunder Spirits (horizontal shooter. part of the Thunder Force series)
Raiden Densetsu

Yes. All of them.
