recently got Sonic wings 2 on AES, it's cool - I really like some of the bosses (the first one looks really cool) and the multiple fighter planes, some of the backgrounds are a little bland, some are great. gameplay is tight and feels well balanced, It doesn't feel unfair. not sure if I prefer it over sonic wings special, but it's a close one.
just totting up my collection, I've discovered I've got about 150 shooters

definitely my favourite genre.
the most surprising thing I found is I have more shooters on the SNES/super famicom than the Megadrive, the majority of which in my opinion are better games than the MD ones, even though the Snes is commonly seen as weak in this regard. Maybe there were just more shooters total released on MD?
the highest percentage of the 150 total is jap Saturn stuff with some truly awesome games (and some complete duffers)
and I have r-type on 3 different formats psone/360/pc engine. for some reason I like the pc engine one the most, even though it's a bit glitch graphically. I love the game but don't play it often, so having 3 versions is a bit overkill.
