Well, yeah. There's a meme I actually saw that demonstrates how developers were back then compared to now. Developers back then, really did care about how to make a game at its best with like...2MB of cache or very little video memory or what little of bits they had to work with.
Today and for a while, with technology as to where it is at where sky is virtually the limit, we've got games that are so poorly optimized, it makes you wonder.
We later saw what Mojang did with Minecraft. Soon as Microsoft opened up its billions, it was hard to resist the offer. Notch has to be some of the most undeserving individuals to have been made rich from, given from how he has acted since Mojang sold to Microsoft.
