Like what Yeomond has said, HOTD4SP costs 250,000 (USD, i’m assuming) and have you guys actually seen the size for it? It takes up almost an entire room. If you ask ZoneX @ DGOA to have it, I don’t know how they are gonna transport it into the arcade - the doors are too small, and is there a cargo lift that can accomodate the parts? I don’t think so. So is ZoneX @ DGOA gonna remove half the games from their arcade? No, i don’t think so.
And imagine if the cost of HOTD4SP is that high, we would need to pay at least 5 dollars for starting, and knowing ZoneX, probably 5 dollars just to continue too.
