After an hour and twenty minutes of gameplay in Mario & Luigi: Bowser's Inside Story, I was able to level-up Bowser to Level 95 from Level 90. By looking at the game timer, I have been playing the entire game for 96 hours and four minutes. This is many more hours than it took me to level up all characters to Level 99 in Final Fantasy II for the SNES when I played it in the early 1990s. Since the enemies of Bowser's Inside Story are visible and do not randomly appear as in older RPGs, it takes time to level up.
Tomorrow, is Level 99.
