I think I’ve already answered this…
I really never took it more seriously than thinking of it as “extra income”. Licensing video game rights was similar to licensing t-shirt rights or lunchbox rights. I let them use my copyrights to do a game, and we were paid (well) for the priviledge.
Overall, I didn’t like doing this, because the games always turned out horribly. We enjoyed cashing the checks, but that’s about it. The problem was that this was in “the old days” and games were on cartridges, not CDs. Cramming a CD-based computer game onto a little cartridge doesn’t work.
Today’s game machines are more powerful than most computers — so, it’s a completely different world.
