Did Namco confirm that? It would be a shame if they didn't. Namco Museum for Switch might have fewer games than their previous collections, but it has fantastic presentation, a snappy UI, and lots of sensible stretching and scanline options (such as a quick toggle to rescale 1:1). It's much more than I can say for Arcade Archives, which are very barebones, terribly slow to start (logo after logo, region select screen, user select screen), and barely serviceable stretching options (no proper 1:1 mode, have to manually rescale a number when portable vs docked).
Galaga 88 is SO GOOD. Especially its use of HD rumble. You can literally feel ships explode.
I need to get this. Just want to get it on sale. Don't usually mind paying good money for games but I don't want to drop the full price on this one since I already own so many of these games.
