Spent a few hours between sunbathing/eating ice cream* playing
Just Imagine. IMO it's the easiest to get into of the software management games (the main others being Software House/Star) and looks to be programmed at least partially in BASIC (?). The gameplay is well balanced, it's obvious when you are risking everything but it's also hard for money to breed money.
Tips for getting a toehold:
-Offer roughly 1/3 of the game's chance of success as royalty
-Don't be shy on pricing! unless I got the promo very wrong it seems you need to price >£10 from the beginning (but less than £14.30)
The biggest failing is that fireproofing your offices doesn't seem to be an option...
