While gathering tools to finish creating and updating my website, I've been putting off the most important aspect of it so far. The game itself. My partner and I have been working on a card game for a long while now that's systematically complete. It even has a very nearly complete set of cards, and it's all ready to be planned out and put into browser game format. I'm not afraid to have to learn and code to put the game up, but I'm not sure just what I should learn to do it. I know I can get everything to work fine with DHTML, since it's capable of doing everything I need. But would it be better (or easier) to go with flash? Or would flash still require some AJAX to make the game work anyway? I didn't suggest java or any MS specific language, because I want mac users or maybe even linux users to still potentially be able to play. Other than the game mechanics themselves, this is what the game would need to be capable of. Generating a room on demand for multiple people to play together. Keeping a permanent track of scores and other variables, for individual accounts, which can be posted elsewhere. Chat functions. I'd be very appreciative if you could give me some insight on which direction I should take this, and why.
