>What are the must play on the list?
Imo, Thunder Force IV, Musha, Battle Mania: Daiginjou, Gley Lancer, Gaiares, Eliminate Down, Lords of Thunder and Thunder Force III are the must-plays.
Personally, I don't like Silpheed that much, but many people hold it in high regard
>I only played musha and I liked it a lot.
You should try Sega CD's Robo Aleste then, it's Musha's followup, just not as great (but still good, though).
Spriggan on the PC Engine CD is also very similar to both.
