Ok so now about 10-11 hours into the game and about to leave the 3rd island and I *think* I'm also finally about to get a ship. So far I'm really enjoying the game. I have to admit that enjoyment is peppered with a whole lot of frustration though lol. The combat can be infuriating at times, but I have to admit it's getting much easier.
Updating your stats does very little it seems for combat (aside from maybe hit % for guns), or at least it's hard to 'feel' the improvements. With that said, the last few hours of the game I've been dumping tons of gold into various trainers and since then I've definitely become more powerful. With some melee upgrades fighting with a sword the frustration is much lower, though I'll admit occasionally even animal enemies remain frustrating at times.
I just got a rifle (sided with the inquisition) and they are pretty fun to use. It doesn't make things that much easier, but at least it adds a bit to the variety of combat.
The best thing about the game is definitely the exploration aspect. Going through the jungles, beaches, caves, and ancient temples is very fun. Feels a bit like Indiana Jones! You find treasure maps (yes, X marks the spot), hints to legendary treasures and weapons, and I really just enjoy exploring the world of Risen 2.
While I am not a fan of the pirate setting I have to admit I am enjoying the way it's presented in Risen 2. It's actually the first RPG I've played that I don't feel bad for being a dirty rotten scoundrel...I am a pirate after all!
Anyways that's pretty much all I can think of for now, and if you have any specific questions just let me know I would be more than happy to answer them.
