I suppose more importantly are they worth buying? If anyone's bought this bundle and has a short impression on each game i'd like to hear.. At least a couple of them look interesting by description alone... edit:
Although after watching the previews for the games, i'll say i'm hesitant to pick up any of them. I've long since fallen from the shmups and fighting genres, leaving the more interesting genres on the forefront, but i wonder if i'd ever play them...
I'm also not huge into SHMUPs, so I only got the pay what you want tier for $1.
The only game I have experience with is Influent, and while it is an interesting idea, in practical application it's not really very useful in terms of language learning, nor is it fun.
However, the other two games looked pretty unique to me and with nice production values. Since they are also DRM-Free and have received very positive reviews, I feel pretty good about how I spent my buck in retrospect.
