Why stop at card-games from other games? Lets make up our own, similar to MTG or something, and create cards with a scripting language.
Heck, I might take a stab at doing something like that myself once I'm a lot more advanced... I can imagine creating an array of arrays for each card, grabbing a deck out of a text file... probably fairly possible.
Well above me for the moment though. Apart from anything else I can only work in text as yet...
Speaking of which, I've planned out an MTG style card-game in pseudo pseudo code, which means I haven't got a clue how to do most of it, but I know the vast majority of variables and functions I'd need, at least to start with. Unfortunately, I also need to understand typedef and similar before I can make something that's coherent. Let alone gfx (though I think I know how I could retrieve them from, say, a text file and paint them - but that wouldn't be that much use I somehow suspect lol). Needless to say, I'll probably never do anything more on it, since I'll forget, but I've planned it at least...
