Wow, four people guessed (or trolled) framebuffer. Interesting.
Facebook makes absolutely zero sense in the context of the sentence.
One could argue Facebook makes zero sense in any context.
Why did you mention Facebook? That makes zero sense
What about you? :p
Faecebook? What's that?
It's absolutely framebuffer here. Games that draw directly to the framebuffer. I assume they meant sprite-based games that don't require 3D drivers, for example.
