How am I ignorant exactly?
I never said there weren't good games, only that so many early titles were really weak in terms of gameplay, with a lot of effort having gone into making games that looked really good, especially when compared to the NES and most anything else (hardware-wise) that came before.
Sega people are always so damned defensive. I like the Genesis, I love the Dreamcast, and I adore the Saturn. I even really liked the Master System for a long time, but its smallish library pushed me over to the NES.
Super Mario World is one of the best games ever IMO, and it was "just a pack-in." That's not an excuse for a game to be weak.
