Yes, you should buy this game.
I played the first Syberia many years ago and I have always wished to come across another game like it, so when I saw Syberia II - wow! I was so happy and I have to admit, I'm pleased.
1.) The graphics are the best I've ever seen for PNC game. My bf even compared it to Skyrim quality - not bad, not bad.
2.) This story is better than the first game. I think this is because Kate has companions in this game, so she feels more likeable and you also get to know the other characters more because well, you're with Hans and Oscar for a LONG time.
3.) Puzzles range from easy to very difficult. The variation is quite nice.
4.) If you left Syberia, feeling incomplete, this will help round it out for you!
1.) Some items in this game are really hard to find. At one point you have to find dry wood to create a fire and it's almost impossible to find it. It also irritating because you're in a forest, yet you have to click in the EXACT right spot to find the item. Annoying.
2.) A few puzzles in this game arevery, very difficult, and no, common sense won't help you.
Overall, I'm very happy with this sequel.
