Good reviews, I did get the chance to play Bulk Slash via SSF emulator, and it is a very good game from Hudson Soft (who IP are own by Konami BTW). The game itself would indeed benefit from a HD remake because the Sega Saturn 3D capability did indeed ham strong its 3D exclusives. Also the game does have similarities to the popular Anime franchise known as Macross aka Robotech for its transforming mecs/other similar elements if you have seen the original Macross series and play this game side by side. And the original 1982 Macross series is an awesome must see anime as well. Yes I know that I am bribing up a non video game thing in response to the review, but being that Anime and Japanese made Video Games often go hand and hand, this is worth pointing out for some.
As for Fighting Vipers critic, I would highly recommend you to do a possible seprate review of the uncensored Japanese version as it does add extra content/is uncensored as well. If you want more info on this check out these links: https://segaretro.org/Fighting_Vipers#History
, but if the diffrences or minor, you can just update the main review and put it in as a note. Also it maybe possible for you to even do a update review its related spin-off game Fighters Megamix which is a cross over of other Sega Fighting game IP's, but it is more in line with the Fighting Vipers series in terms of Gameplay. And like the first Fighting Vipers game, has also regional/censorship changes with info here: https://segaretro.org/Fighters_Megamix#History
Also a dumb down Sonic Spin-Off game called Sonic the Fighters also has relationship with the Fighting Vipers series with more info here.: http://info.sonicretro.org/Sonic_the_Fighters
, which is available on the Sonic Gems Collection on the GameCube.
