Cod and ragnarok would be great
Decent selection, but just be wary of higher pricing on older titles. New titles like M+R:SoH is a safe choice, knowing it wouldn't have enough time to have been cheaper in the past (plus Nintendo having notoriously tame sales).
But there are plenty of titles I've seen in these collections where they took a game that has been on perpetual sale & bumped its price back up to MSRP for inclusion in these sales, which ends up making the overall deal roughly the same at best, or actually cost more at worst.
Of course I read about this sale after spending my money today on video games separately lol
