So 5 years later, I'm finally getting around to working it into the site.
I would say it is probably a fairly standard online card battle game, but I'm not familiar with many of them so I couldn't say with any certainty. Obviously it's themed around "retro" stuff, so the characters you're battling with are a variety of familiar faces from the '70s, '80s, and '90s.
I wish I would have gotten around to this sooner, but other obligations, a lack of knowledge of how to rework the code, and other issues kept that from happening until now. Over the years, I've learned a lot more about code, but still only a tiny, tiny amount.
I think this will be ready to go sometime this week, so keep an eye out.
