I gave Eschatos a try yesterday. Actually, I just wanted to take a quick look, fired up original mode on easy... And played for about 1 and a half hours, not noticing how fast time was flying by. A very good sign, hehehe.
What can I say? I'm actually digging the simplistic graphics, they have a very nice old-schoolish flair combined with nice 3D-graphics. The controls feel spot on and those formations remind me (in a good and retro-way) of the times of galaga and therelike. And the music... Wow, I love it, the music is very suiting for this game, and actually quite catchy.
So far it's a lot of fun, it has a very good "feel" that makes me want to come back for more. And I haven't even touched JSS and CS. I think I'll concentrate on Eschatos itself atm, going for pure survival for the beginning.
Yeah, I'm glad I chose this game over bullet soul.
