The first Playstation game of 1995 and the first 3D fighting game of all times. Probably not the first polygonal fighting game but the first game with free movement around the arena, and the father of games like Soul Blade.
Yes, i mean, the first 3D fighting game with free movement. The first game where 3D made sense, aside replays.
I liked Battle Arena Toshinden 1 a lot. I played it to death back in the day and it was my first psx game. Even at the time, I felt like BAT 2 was a visible step down in quality. 3 also seemed lower quality and the animation seemed much jerkier, but there was so much new content in terms of characters, moves and music, that I still had a lot of fun with it.
I am still a huge fan of the Toshinden Series. Battle Arena Toshinden and Twisted Metal were the first two games I played on Playstation at my friends house and are the reason I asked for the console that christmas. I like the later games in the series, still need to get puzzle arena toshinden and Toshinden Card Quest (2 obscure japanese only games). One of the stand outs of the series had to be NiToshinden (Toshinden Kids, Kinda like the VF Kids game) and the Gameboy version of the first game. I will need to do a video series on these games when I eventually have them all.
The games pretty awful to look at or play now, but I do have found memories of it. Seeing as there wasn't much to choose from at the time the first Toshiden kept me pretty entertained. To bad it felt so sluggish, if I played a bit faster like Tekken, maybe it would have had more success?
Can anyone confirm what @textfiles says: The developers didn't have a development tool and they reverse engineered it? Sounds like BS to me as it would have been an infringement of their license!
It also has Super Gameboy features so if you run it on your Super Gameboy on your SNES console it will have a custom border and color palette.
