Given how touch heavy the game is, I don't think there's too many port options for Severed so a Vita release makes sense. The Switch (in handheld mode) seems like a likely destination for a port of this game though.
The last 6-7 orders I placed with GS have all been game only... I don't think I've gotten a case with a GS game in years when ordering online.
Same here. Since I care about cases and such I only buy from GS in-store now. Tweeg seems to have historically good results, though, so fingers crossed for him.
