Due to my lack of interest in the PlayStation/Xbox platforms, I've played every installment except Knight and Asylum, but if the rumors of Arkham Collection coming to Switch are true, then I'm looking forward to giving them a try, even if it turns out to be one of those dreaded Cloud releases. From what I've seen and heard, Asylum is good but suffers from first game syndrome in some areas; meanwhile, Knight looks gorgeous and plays well, but has too much tank gameplay, a lackluster story, and a few bugs.
Personally, my favorite installment is Origins on its story and crime scenes alone, but who knows? That may change... ?
