Foxhack: LucasArts HAS published a lot more games than the Scumm / Star Wars / Indiana Jones stuff, you know.
Delixe: Battlehawks 1942, Afterlife, Maniac Mansion, Day of the Tentacle, Zak McKraken, Full Throttle, Loom, Night Shift, Monkey Island, Indiana Jones, The Dig, Secret Weapons of the Luftwaffe, Sam & Max, Dark Forces, Jedi Knight, Rebel Assault, X-Wing/TIE Fighter, Armed and Dangerous, Grim Fandango, Galctic Battlegrounds, Empire at War, KOTOR, Shadows of the Empire, Thrillville.
Yeah they could get 25 games out of that list but that is assuming GOG will get every Lucasarts game and we know from the past just because a publisher signs it doesn't mean we get the full catalog.
You can get more than 25 games, even including some missed titles. Monkey Island and Indiana Jones alone make up 6 games. (7 with infernal machine) Yet you have them as a mere two entries. Sequels are titles too.
Jedi Knight is 4 or 5 titles. X-Wing is another 4.
