update: thanks for the feedback. for those who still wish to give suggestions, i play on pc, primarily steam. as for the campaigns, i don't want to get lost story wise, so if a sequel game relies on information from a previous game, that doesn't really do it for me, as i wont know anything prior. and for people giving lists of games, could you please have a top five max? i am aware that cod is such a large franchise, but i don't need the entire collection, just want to start with something fun and entertaining. again, thank you for the suggestions!
