Devil Survivor Overclocked adds great new features, unfortunately the first play thru is still a major grind fest.
Combat is standard turn based srpg, you and your characters battle demons on a grid battlefield and instead of one on one combat there are two teams of 3. At the end of combat you receive experience points and money, the money is only used to buy more demons from a demon eBay like auction. As you go up in level you will be able to fuse two demons together to get new stronger demons. At the beginning of every battle you can pick one new skill you would like to learn per character, if that character defeats the demon with the skill he/she picked then that skill is learned and goes into a skill pool that any character can pick from so long as their attributes are high enough.
Overall this game is very good but there is one thing that I didn't like. The difficultly on the last section of the game where you pick which ending you will take is far harder. The time required to raise your level to a point where you can finish the game doubles the time spent playing. Hour after hour of fighting the same battles, just so you can then progress the main story. This is just plain stupid, and ATLUS needs to stop doing this in their RPG's. The most improved thing in this game IMO is the adding of the voice acting, it is done well and never got annoying.
