According to the stat menu I'm only about 23% through it. Feels like I've been playing for a while, though. I have been completing every side quest I come across. Just wondering. --- "Search him.

It's not 23% through the campaign, it's 23% completion, which includes Riddler's trophies, side quests, etc. When I finished the game I had 48%, and that was with a bunch of Riddler trophies collected. You're probably about half way through.
Somewhere around 40-50% probably.. go to stats and that will break down your total completion percentage for the main story, Riddler stuff, side missions, etc. --- Modified HAF 922 | AMD 990FX | Phenom II X6 1090T | 2 GTX 460s | 12GB DDR3 1600 | 60GB SDD | 3 WD Green HDDs | LG Blu-Ray RW Drive | Win7 x64
