Clover Studios/Platinum Games: Viewtiful Joe, or maybe Okami.
Konami: MGSV took them down. Not because of the game, but because of the way they dealt with Kojima and the staff at Kojima studios.
SNK - I'd say KOF XIV has gotten them back on the map to where they were during the SNES days.
Bethesda: The Elder Scrolls IV: Oblivion made them into a mainstream developer. Skyrim made them top-tier.
THQ: WCW vs. NWO: World Tour on the N64 made them respectable, Udraw killed them.
