oh, yeah, would not get an 8yo who dislikes anything sexual into Borderlands, one of the running themes throughout the series is sex jokes - the sex jokes did ramp up in BL2, but there were still plenty in BL1, as I recall.
unfortunately there just aren’t many splitscreen coop games anymore, and especially not looter-shooters, most of ‘em are one player per TV with online multiplayer. this is a very sad state of affairs but it’s so rare for a game to buck the trend that I can’t think of anything other than Borderlands.
if you drop the loot requirement, I think the SW Battlefront classic collection would fit the splitscreen shooter requirement? but yeah I’m drawing a blank otherwise.
hell yeah, awesome that y’all have open communication about these things. hope the kiddo loves Borderlands, it’s one of my favorite co-op game series.
note about Battlefront: there are the new ones that have a splitscreen mode but it’s kinda a glorified practice mode for the online-only modes, and the remakes of the originals (Battlefront Classic Collection) that have proper splitscreen campaigns but (from what I’ve heard) poor online play.
