Thanks man, I just bought a XB1 last week so I'm late to the party. I think I'll start with DR3 Apocalypse Edition. It's $20 on Amazon right now. I'm sure it's been cheaper, but again, I'm late to the party.
I'd also recommend getting the Super Turbo EX+ a(lpha) or whatever DLC for the game. It sadly isn't included in the season pass/Apocolypse Edition, but is very worth it if you are an old school Capcom fan. It's even fun without friends, but the last level is pretty difficult by yourself.
Personally, I enjoyed DR3, the SP DLCs were ok, but the Super Turbo one was excellent. I'm enjoying DR4 so far, but the DLC doesn't interest me, so I'd second skipping the season pass on that.
