Kingdom Hearts 2

Action RPG from Square-Enix. Played on PS2.
Collaboration between Square-Enix and Disney, so has characters from both companies' products. While this enlarges the potential audience, it's also a downside because no one wants to hear 'GAAAWWRSH SOMMMEBODY COME QUICK' from the hideous Goofy while they try to concentrate on fighting enemies.
Thankfully the game itself is actually fantastic. Graphically, it is very impressive, and succeeds well in emulating all the locations from disney films; each planet in the game is based on a disney film, so every area feels unique, although this means you have to torture yourself going to Atlantica. Thankfully, pirates of the caribbean world and nightmare before christman world are awesome. Gameplay consists of exploration and combat, and the combat is where the game excels. There are also shoot em up sections between worlds which are actually quite well implemented.
The combat consists of using physical attack combos and magic, and while fights are on the whole quite easy, the attacks are so stylish you end up having alot of fun playing. There are also alot of combination attacks and limit techniques; but the best feature has to be the context sensitive reaction commands. Hitting the Triangle button at the right time during battles can shift the tide of battle, as you pull off a huge attack, or block a potentially fatal strike. There is even a section where successive triangle inputs make you jump across skyscrapers hurled at you by a huge monster. Imaginative, physics-defying, insane... and amazing to watch. And since these differ for every big fight, it helps make fights cinematic and unique rather than just button mashing X. Mid-fight you can also transform when a gauge is built up, which is extremely cool but can also put you at a disadvantage if you choose the wrong form.
Overall, the game is quite easy but so much fun that doesn't matter, and there are optional battles for players who want a challenge. The narrative is also interesting enough to warrant playing through the game. 9/10.
