There's a lot of it too. It's like the Westwood v Blizzard output. Back in the day, Blizzard occasionally released a game and it was on the shelves for a decade (like Starcraft). Meanwhile there were like 50-billion Command and Conqueror Dune 2 Red Alert Terra Nova Spy Ops Edition games. If you looked at it as a whole, you'd say RPGs were repetitive and kinda sucked. But you'd miss out on the bangers like AoE2 (Dune 2000 wasn't bad either for Westwood).
Quantity verses quality. Like how Ghibli and Trigger try to smaller amounts of high quality stuff, versus companies that make any random comic they can find into a series.
