But I definitely get it. A quality plug-in arcade setup is gonna cost quite a bit, regardless of the actual games themselves. And it makes sense for a game like AvP to be reserved for this sort of treatment to skirt possible rights issues, even if it comes off like really shitty baiting. You really gotta be into this sort of thing to jump in unless they really go all out.
What gets me is that I'd easily pay double the price of the Beat 'em Up and Street Fighter collections if they released even just these five known games in a similar quality bundle to those. But now, even ignoring the price, I have to worry about stick quality for sticks that I actively do not want, emulation quality/features, and end-to-end lag (I have my doubts that this thing will be as lagless as my Gsync PC).
