So your saying a new platform doesn't have the decades worth of trial and errors that arcade gaming has? I can bring up plenty of really shitty early arcade games from the 80's, plenty of crap. Heaps of it. I think this whole comparasion isn't even fair considering how long arcade gaming has been around. I will say one thing, it has gotten worse (arcade gaming) over time while Mobile is at least improving.
Tho in the end of the day I rather SEGA just drop arcade and focus on PC/Consoles/Mobile. In the end its all about who gets to play your experiences, not what is nostaglic (aka a dead scene like arcade gaming).
