Making something that's isn't exclusive to html5 would certainly be a step in the right direction for me, but I don't want to end up using some engine where I cannot even play the game on my own system *coughelectroncough*. I have managed to tackle RPGs, platformers, puzzle, arcade, and shmups. I would like to try my hand on some old school style rts as well, down the road, given I already have experience with making a mouse-based game and building stuff on a map (courtesy of a tower defense game I made... should probably update the code and put it on here, some day). However, I know little-to-nothing about making it multiplayer.
