1st game has great designs and it's a bit like Street Fighter but in 3d. You have all sorts of different characters from samurai to knight to assassin to dominatrix, plus your Ryu/Ken wannabees, and a hidden Akuma boss. The normal boss Gaia looks like some japanese warlord with scorpion stings coming out of his back, and his level is this giant transparent vortex that looks crazy good.
2nd game revamps the designs for the worse while keeping the wobbly graphics and laggy controls. The music now all uses the same metallish instrumentals so it all sounds the same except for Gaias theme. It also rebalances many old moves so they become crap. For everything it added, it also removed something good from the first game.
3rd game is an arena fighter with explosion moves you can do. It's actually pretty crazy how much juggles you can do, and it looks psychedelic too. Every fighter also gets doubles who are copies in many sense. So you can end up with Catwoman, Jason Voorhees, Erol Flynn, Michael Jackson, it's pretty insane. Not bad for a party fighter, the juggle system and the wall bounces make it a lot of fun, plus unlocking all the clones is worth it.
4 added a crap new cast and tried copying Soul Edge, while turning the super moves into cinematics. Avoid it.
>>11797927>They put quite a few bonus features in so it's definitely got some things to exploreFirst toshinden has fuck all bonus features other than a hidden super boss if you can 1cc the game, and the game demoing your desperation/super secret attacks if you beat Gaia/Sho, respectively. I think you only get your character ending (text only) if you 1cc the game.
