This. Withered tech has great value in that you know the kinks, it's relatively cheap to develop for, and you're relatively certain that the specs won't be too powerful for the majority of your audience. It also saves on processing power and load times!Yeah that's a fair point, but so many businesses don't do that, include really big corporate ones, because of the sheer burden of getting people up to speed on the newest engine. UE5 is a remarkable engine, and very flexible (in theory), so could be good, for sure.
I guess the advantage here is the product doesn't exist, so however long it takes, it takes that long. It's not like they're trying to keep something going.
