I really enjoyed Origins and Odyssey. The combat was far more fun than any of the other games, and the settings are amazing periods of history.
As with all RPGs, levelling up can make it a bit silly if you look at it through a real life lens. Having wiped out a Spartan camp by myself, with little difficulty, at times I then have to tiptoe through the area next to it, because the local wild boar is several levels higher than me.
RPGs are full of silly things like that. Take Skyrim. Bandits can be brandishing ebony weapons and armour, which sell for good money in the nearest towns. If they just sold their weapons and armour at the blacksmith, they could retire to a nice house. But no, that doesn't make for a very fun game, so they live in the open air in a ragged bandit camp, trying to ambush travellers to add to the 17 gold in their chest.
