It's nowhere near even. Not even fucking close. Not even factoring in historical discrepancies, but only the last 5-6 years, Europe has disproportionately got the shortest end of the stick in these matters. Whether it's buggy releases, late releases, releases with content missing, we just get fucked in one way or another.
Of course there has been some high profile NA delays, especially when NoE localised a bunch of games, but that is something that happens infrequently. I could name you a handful games out in the US, or out very soon, at any given time that either don't have an EU release date or have one that is significantly delayed from the American release.
What's delayed in North America recently? Steins;Gate, Yoshi's Wooly World, and quite possibly Devil's Third? Have I forgotten anything? Meanwhile, on our side of the pond Atlus' entire 2015 library is delayed by at least a month, though more often than that longer. So that's 6-7 games there (Etrian Mystery Dungeon, Untold 2, DeSu 2 Record Breaker, Persona 5, Persona 4: Dancing All Night, Legend of Legacy, and Lost Dimension are the ones that spring to mind). Guilty Gear Xrd only just came out, and then ASW announced the newer version which is fucking galling. Though it's all okay, because at least we're getting the games! :3
Sorry, rant over.
