2009 - they were producers, but the development was done by Raven Software and published by Activision. So not really involved other than owners of IP? New Order - not at all, maybe as engine developers. Right for that IP were transferred to MachineGames in 2010 right after ZeniMax got hold of them. As for Doom 2016 - they enlisted a lot of outside help after Doom 4 was scraped. Bethesda's game directors helped them a lot because they already figured how to make "old ip" to sell well with modern gamers (see Fallout 3). side note: I don't think id managed to get deliver a lot of good games since John Romero left. (just like John Romero didn't deliver many good games since the separation) John Romero and John Carmack were like a dream team, but without each other it was meh.
