The creators of Card Sagas Wars decided to publicly release the game (or what they had worked on up until 2011) to let us try it out. There will be bugs and stuff, but I remember seeing screenshots and videos of this game back in the day and being very excited to play it.
It's a very pretty looking game. Check out this stage from Ocarina of Time for example:

Also, give a thanks and maybe a follow to Dani Oliver on Twitter if you appreciate this:
