I've had a long-standing rule to avoid getting involved in any sort of crowdfunded activities. I didn't donate to Shadowrun or Wasteland, but I did buy and enjoy both of them (I'm plugging both of those games right now, just so you know they're good). I haven't...
The Good: The one hit kill theme is like no other fighter, good amount of modes, two player is awesome, awesome first person mode
The Bad: Blocky characters, lame story mode, enemy AI is too predictable
I remember hearing about Bushido Blade back in the day but wasn't old enough to understand the game. Now that I've played it I can see what the hoopla was all about. Of course now-a-days BB feels really old and somewhat crippled. The game has tons of modes and an awesome first person mode. The story is really lame and there aren't enough characters. The graphics are alright but the characters are really blocky. The whole hype thing was you can die in one hit. It was like the ultimate fighting simulator. You hit their legs they go on their knee. You hit there arm they fight with one hand. You can choose your weapon of choice before combat as well. Also, the best thing here is the multiplayer of course. The computer AI is really predictable and is either too easy or way too hard...never in between. The game a huge blast with two players though since you never know what the other person will do. While the control scheme is awkward if you're used to today's fighters it's doable. Play BB if you really want to play a classic gem and want some good old school two player.
