I added four more shoot ‘em ups on Steam:

>Eschatos
(I like all these guys’ games)

>Batsugun
(I saw someone doing 1cc on this Steam version and decided to try it too, even though I already have the game on MAME)

>Parodius thing
(I don't even know what game this is, but I liked the art style)

>Blue Revolver
(I've only heard of it, I don't know the game either)

>IKaruga
(it costs $2 on sale + regional price, so I decided to buy it even though the game is too difficult for me)
