edition... or version all D&D and as such the same game.Then what terms would you use?
they are all D&D so the same game, 2e 3e and 3.5 are all different editions of the game (by any use we used prior to last year when wotc tried to redefine edition) Bo9S is a splat book optional add on to the 3.5 edition.If 2e and 3e are editions, it seems wildly inaccurate/confusing to call 3.5e or Bo9S an edition.
again the game is D&D... it never changes the edition does, and the optional add ons do.However, it seems wise to me to use the more standard term of edition for revisions to an existing book/game that is otherwise fundamentally the same. Then you need something else for major overhauls like 3e, 4e, & 5e. I was saying game, but maybe there is a better term.
so D&D (game) 5e (edition) useing all the books (what add and options avalibul)
or D&D (game) 3e (edition) phb only (what add on and options)
or D&D (game) 1d&D (edition) phb plus 1 splat of your choice (what add on and options)
or D&D (game) 2e (edition) darksun modifications plus psionic handbook and barbarian handbook (what add on options)
or D&D (game) 4e (edition) PHB 1 &2 and the swordmage from forgotten realm book only (add on and options)
