Re-Logic (Terraria’s developers) have already gone on record saying, "even if Unity were to recant their policy and statements, the destruction of trust is not so easily repaired.” That’s the stance I think every developer should be taking. Unless you have a Unity game that can be released by the end of the year, all devs need to seriously consider switching engines.
Looks interesting, but I gotta be honest: when I click on the Steam page and the first thing I see is a cash shop to buy "Epoch Points" for this early access game? That's an instant turn-off for me. I'm sure it's not as predatory as what Blizzard did with D4's monetization, but I don't want it in my games, period.
