After buying Otogi 2 over a week ago, I finally got around to checking it out today. While I did like the original Otogi, there was something about it like it wasn't polished enough. Otogi 2 takes the original, throws in more of what made it great, and tops it with so many needed extras. Making it quite good.
First of all, after playing about 5 levels or so I can say that it's not as hard as the original Otogi, which is a godsend. Otogi 2 is pretty much more of the same as Otogi, mainly being complete a mission objective which is usually killing, or destroying everything in a level. This time however you are able to select your next mission, usually from 3 or so on the screen, and then select one of 6 characters to use in the mission. Each character is very different from the others, each with very distinct attributes and weapons. This is a great help as certain characters are better suited to specific missions.
The graphics and effects are improved greatly over Otogi also. The graphic have been polished and the effects have much more style to them, making for some truly great battle scenes.
The controls are a little more solid this time round, though I still have issues with the camera control. It's a little slower to refocus behind your character when you tell it to, and also there seems to be a limit to where you can look which can hinder things at times.
The new Havoc mode is also quite interesting. It's basically a load of side missions where you are giving a set task to do usually in a giving time limit. Going by the name you can pretty much assume that these missions focus on you destroying a lot of things in a given mission, and they pretty much seem to be that. A nice break from the main game.
Overall I have to say I'm much more impressed with Otogi 2 than the original, it's just more fun and enjoyable. Also having the extra characters is a blast, they are so varied that you get so much more satisfaction when using the right one for a mission.
