Interesting history but I was shocked with all the negativity about Altered Beast. I think it's great and one of my favorites for the system.
Never heard of Last Battle. Might be able to have some fun with it if I stop that health meter from depleting. Grabbed it for some possible hacking..
Space Harrier II and Super Thunder Blade both look terrible, SH2 especially. LOL if I accidentally bought that at launch I would've been pissed! From the ridiculous looking flying around the screen to that God awful dying sequence and howling. That's what would have played in my head when I thought of Sega afterward.
Thunder Force II looked good. Probably set the bar in 1989 but with those 6 launch titles available, I'm sure people learned to like what was there and forced themselves to play. Just like with the 2600
