2009 was the year of “fixing” beloved Simpsons things that weren’t broke to begin with, starting with the godawful new HD title sequence and ending with an iPhone version of the Simpsons Arcade Game from 1991, one of the very few Simpsons video games that is still remembered fondly.
What’s different: The storyline (no more Smithers stealing Maggie for some bizarre reason), you can only play as Homer, you can slap him to revive him, new design (as far as I can tell, it looks like a modern episode and not all pixelated), and characters/locations that weren’t around or as iconic in 1991 (including the Republican Party Headquarters and Rich Texan).
What’s the same: The basic controls (I think?), and the dated Binky-with-a-ghetto-blaster level transistions (which I like). [United Simpsons]
