Quoted from zacaj:
2. Built my own boards, PROC costs too much
I don't understand why anyone would do that strictly on price. To learn, yes, for fun, yes, for price? That seems ridiculous. You could accomplish so much on your custom game in the time it would take you to create your own board. Not to mention debugging time of that board, doing OS stuff, etc. when all of that has already been done with the p-roc.
