All to GameFreak or The Pokemon Company, since it would have a better profit return than anything else. As far as I know, nothing outsells Pokemon when counting all video game sales worlwide--and even if GTA beats it, which I doubt, that would be offset by substantially higher development costs, as well as the fact that GTA doesn't have T-shirts, stuffed animals, card games, an anime series, its own Japanese amusement park, and every other aspect of the marketing blitz.
After I became a billionaire off of that money, then I'd go ahead and give some money to other companies. Something like:
-A substantial amount of money to Namco to remake Tales of Symphonia with the Japanese voice option and no less than 100 different outfits for Colette. And possibly a new sidequest to make Presea regain all those lost years and grow older.
-A medium amount of money to Tri-Ace to produce a real sequel to Star Ocean 2, with 2D sprites on prerendered backgrounds. Or even just a remake for less money would suffice, I guess. Kill the bad translation ("Fighting Man") and world map slowdown, and get a consistent pronunciation for "Rena."
-As much money as it takes to get AKI to make wrestling games again. WWE, TNA, ROH, it doesn't matter. Without AKI, wrestling games are completely unworthy of a purchase for over ten bucks. Maybe not even then.
-A small amount of money to Square-Enix to port Chrono Trigger to the GBA or DS. I'm assuming that it can't cost that much.
-A small amount of money to Intelligent Systems to make a "War Room" style system for the Fire Emblem series, which drastically needs that since otherwise Advance Wars is kicking FE's medieval pants off.
-A medium amount of money to Amusement Vision to create more games like F-Zero GX.
-A medium amount of money to Camelot so that they can make a GBA/DS Mario Strikers game that, if Mario Tennis Power Tour is any indication, would absolutely slaughter the GC game and its astoundingly barebones design. And yes, I know Camelot didn't make Mario Strikers. That's exactly my point.
