I've actually been building proof of concepts for a PC version of the game for a while now. I've been trying very hard to improve speeds using just the .NET CLR, but it looks like I'll have to begin looking into either making or borrowing a proper image library for this. My own very basic algorithms just aren't enough to keep up - I'm hoping to have it run on 512MB RAM computers, although it looks like whoever's interested is going to need 1GB to run this well - it currently runs using just 8MB of RAM - but it can easily balloon if I decide to preload resources into RAM. We'll see.
Oh yes, card images copyright Wizards of the Coast, or Hasbro, or whoever owns them. Definitely not mine.
