Protoss: Actually there are many games that still could be added.
The Ultima series. Terra Nova - Strike Force Centauri. Comanche. Armored Fist. All LucasArts adventures. Some non-LucasArts adventures (like Inherit The Earth and Shannara).
And that is not even the tip of the iceberg, because to have that we would have to add Diablo, Warcraft 1 and 2, Cultures 1 and 2, The Settlers 1 to 4, the Fugger series, Hanse - The Expedition, The Great Art Race, Project: Nomad (space sim from 1994, not to be confused with Project: Nomads from like 1999) and many more.
Classic RPG, not a classic RPG, not a classic RPG, not a classic RPG. None of them is a classic RPG. None of those are classic RPGs (like that one that isn't a classic RPG and that other one that isn't a classic RPG).
One classic RPG, two not classic RPGs, two more not classic RPGs, four more not classic RPGs, a series of not classic RPGs, not a classic RPG, not a classic RPG, not a classic RPG that is not to be confused with another game that is not a classic RPG and many more which might include some classic RPGs.
