Actually, Spellforce has a lot of RPG. It's far from innovative RPG, but I was quite surprised to find what I did. I'd say (in my 8 hours of play) you spend 55% of your time doing RPG quests, the rest is waiting on your village to build up and running around getting into fights.
The RPG questing is pretty ordinary. Stuff like "I lost my master's spectacles, if you see them, could you return them to me?" or a drunken dwarf who demands you bring him some good dwarven liquor. So far I think everything has been of the "bring item X to me and I'll give you item Y or send you on another quest" or something to that effect. Like I said, not innovative, but a long way from being strictly RTS. In fact, at this stage, I'd say RTS isn't the full focus of the game. The focus is on the player (your avatar) and what he has to do to complete his quests and advance the story. The RTS aspects are merely a means to an end. For example, you have to clear an orc camp, the only way to do that is with an army, so you spend the next half hour building up an army and then you go assault the orc camp. Once that's done you just keep your army around in case you run into another camp that needs clearing, but you can often complete quests without the help of others (like I said, at least that's true at the early stage I'm at in the game).
To expand on what I said about the focus being on your character, there's some degree of tunability in how you develop your character. Often quest completion will grant you experience points, as will vanquishing foes. As you advance, you choose where to invest your skill points and how to increase your stats. Those, of course, determine which weapons, armor, and spells you have access to. So you can voluntarily complete non-essential quests or kill those wandering monsters if you like, to get just that little bit more XP so you can advance a level and up a skill in order to use this really cool item you've been carrying around for a while. It's an interesting dynamic to be sure and certainly a different mix than other games.
