I know what you're saying Justin. To directly answer the question, yes, a good combination of 2 "games" from the drop-down is D&D + Old School Revival, or AD&D + OSR. Of course OSR isn't really a single game but refers to the widespread rebirth of popularity of clones & simulacrums of early D&D, which could be: Basic Fantasy RPG, Dungeon Crawl Classics, OSRIC, Swords & Wizardry Labyrinth Lord anything like that combines well with original D&D or AD&D All these games are cross-compatible with D&D and the campaigns frequently combine official D&D adventure modules, with the newer clone rule systems which are available (sometimes for free). Or vice versa: using new OSR modules and megadungeons, with original D&D rule sets. Some GM's might also tag this D&D + Other Games, if not OSR. For this reason, allowing the flexibility of listing 2-3 games in the field has proven useful. But the games that list 5-10-15 games seem like too much, to me.
