When Does a (Gaming) Duology/Trilogy Hit Its “Peak”?

[Leynos]

In my 30 plus years of playing SEGA games this is the first time hearing Sonic 3 and Knuckles is considered peak. It was always Sonic 2. Mark Cerny and Co did an amazing job. The most I hear about 3 is MJ helped with the music and the add on. Fine game but it wasn't Sonic 2. Gears of War peaked at 3 tho. ZOE has 3 games. 2 mainline and a handheld game. Peaked with 2. The Data east Fang series. Wolf Fang is clearly the best.
