If you like loot grabbing hack n' slash, you'll love Sacred 2. The story is goofy, but not more nonsensical than most video games.
I'm taking the approach of avoiding a lot of side quests to start with. It's distracting to have 10 going on at once. Most are very simple. If I could do quite a few at once, I could be more economical. Some of the map and quest designs result in repetitive runs, which is probably the most frustrating part of the game. The second most frustrating is not being able to save anywhere you want, although you can save anytime. You just don't reappear where you saved, you reappear at the last activated checkpoint pillar.
I still can't figure out the upgrade systems, and my Seraphim is at lvl15. Points to upgrade her appear with lvl ups, and I use those to do the spells. I am guessing that using multiple runes for the same spell doesn't help at all?
And the weapons upgrade system with the slots is confusing as well. I go to a blacksmith and he offers to upgrade a couple of crummy weapons, not my better stuff. Can I do upgrades myself and attach stuff? What objects can I attach?
This is the main reason why I like D&D universe stuff- the familiar names and approach can make it easier to navigate without having to learn a whole new system.
