I love digital comic games, I really wish more of them were in English. The Sega CD Snatcher is the only Snatcher game that was released outside of Japan and the Sega CD version didn't even have a Japanese release. Pretty interesting, eh? I guess Japan didn't really need it though since they were focused a lot more on PCE CD anyways, so at least we scored for once.
I saw screenshots and videos for Dead of the Brain I & II remakes for PCE, it looked awesome. There are some other digital comics I would love to play, like 3x3 Eyes which you showed us the excellent opening cinemas for with SCD and ACD format .
Ranma 1/2 "2" is totally playable without any japanese knowledge and its a really well done, fun "digital comic".
I haven't played it since finishing it years ago, but I think that most or some of the commands were symbols. Either way, its very simple to control, very straight-forward(especially compared to Snatcher) but still feels very interactive.
One of the chapters is a game show thats very cool. The graphics are really sharp and colorful. I feel like playing through some of these games now after reminiscing about them.
I tried out
Dead Of The Brain and didn't have much fun. 1 looks pretty ancient and 2 seemed too convoluted. They may have been using the novelty of gore as a drawing factor over gameplay, but I never really played far enough to figure it out.
Gunbuster Vol.2 is about as straight-forward as they come. Its more of a fmv/choose-your-own-adv game and if you make any mistakes, you start back at the last decision point. I think that there are different paths with different endings, but I only played through it once and it was nice but not too much fun.
Policenauts for Saturn was very cool and lots of fun. Like Snatcher, there's a lot more work in it, but its also very rewarding. It also seemed easier to understand than Snatcher. The Saturn version is supposed to be best, but the PSX version should also be near identical, with slightly cleaner fmv, longer loads and a few missing graphical effects(Saturn exclusives, ironically mostly transparencies I believe).
The 3DO version's claim to fame is that it still has the talking heads from Snatcher. But the game saves aren't compatible with a U.S. system, so you'll have to emulate it or buy an import console.
