As a mostly PvP player, while I don't think single player campaign/PvE is a necessity for me in most PvP-centric games (I've yet to play the single player campaign of most of the CoD games I bought :P), the original Titanfall did not do nearly as well as it could have because it lacked a single player campaign mode, which Respawn rectified in Titanfall 2. Full disclosure: I never finished playing Titanfall 2 campaign either... but I also think it was a misstep to not have a single player campaign for the first one just because it was a new IP, new 'verse, etc. that you want to immerse people in via a campaign/story/single player mode, to draw people in and get people immersed in that world, so that when it comes down to the PvP, it feels more like you're literally existing in that world and 'verse. Without that initial single player campaign that draws people into the world, for all of Titanfall's advances in PvP mechanics, it reduces the game to simply mechanics with no appeal beyond that, no investment in the game or 'verse beyond simply getting many kills and plays in a match. I think there is more player retention and engagement to be had when people are not just drawn to the mechanics of a game that has PvP, but also has that PvE component that gets people invested in the world and 'verse, and then hopefully even PvE-centric players might be drawn to trying out the PvP. Destiny franchise's major issue is lacklustre PvE that is repetitive, unrewarding, lacking in meaningful choices in terms of how your character relates to the world, the 'verse, and importantly, the NPC heroes that Bungie has populated the world with. When nothing you do in the game seems to matter to the end user, and there aren't enough sufficient outlets for roleplaying or otherwise having your avatar act as if they are an actual living person in that world, it breaks people's suspension of disbelief about all the other fictional and unrealistic elements of the game, which leads to people not becoming invested in the world, the NPCs within it, the lore, the single player campaign stories, or indeed, even their own characters. And I think that very much leads to increased trolling, harassment of other players, etc. simply out of boredom and frustration. I honestly think the Destiny franchise would be best served played out on cloud servers only (a la Google Stadia), but with much, much, much larger PvE worlds where in-game player choices actually matter, where you feel you can effect some kind of change (positive or otherwise) in the world, where the things you do actually matter. Allow players to build a house, or a home base, or something, custom digs you can call your own but you can invite other players to check out if they're interested. Allow people to tame pets or other creatures, decorate them, name them, have them fight alongside you in every activity. --- This was supposed to go into a subthread re: PvP
