This is indeed interesting, how many titles have you planned? you want to release about 3-4 per year or more if possible ?.
arguably if you keep your display routines well documented there is quite a few systems that will enjoy your games, not to mention the Atari ST
How many coders do you have? will you be offering freelance work ? or concept / development franchise (like in the case of WORMS with team 17)
to maximize sales, have you considered hand-held console markets ? (its here there is proof even a crap game sells!)
deffinately food for though, and one i would be most interested in.
if its that kinda action for your pc, then surely you could download them pop-cap games.... there bloody addictive if nothing else....
