Dunno if anyone's interested, but I came across this recently. It's by far the best free online game I've ever seen.

It's a collectable card game that rivals just about any other I've played before, including Magic: The Gathering and the like. Brilliant simple gameplay, great artwork, customizable decks, collectable cards, the works.

Worth checking out if you're into that sort of thing.

It looks cool but I have a feeling you could end up spending a lot of dough to make a good deck.

You could, but there are ways around it. You get points to spend on cards after each game (4-8 per game), and if you go in the tournaments you can get a lot (even if you enter, lose one hand and leave you get 50). Tournaments run every 2 hours.

And you get about 100 games out of the lowbie levels where everyone uses basically what they started with, so if you don't love the game after that you can walk.
