Played on Windows Vista 64bit (run as admin).
Ok, so I bought G2 off the back of enjoying my impulse purchase of G3(still yet to complete), and i must admit, at first i was highly put off & dissapointed by G2's controls. Untill I figured out a good keyboard combination for myself. Simply, using the WASD keys is not workable i found, but the arrow keys make the game feel like any other RPG eventually.
One other problem was that the FMV sequences, were black screend with the audio in the background, but sometimes they randomly played, which was annoying. However this didnt spoil the game for me, as there are only about 3-4 FMV's to watch in the whole game, and you can view them online anyway.
Overall, after getting over the control issue, i am finding G2 to be a delight to play. I found this game to be much more challanging to play than G3, as experience points were harder to get, and train up your character. But this made for some great battles, and having to use battle tactcis to take down more than one foe(gradually you will become stronger and feel a great achivement when defeating earlier enemies that were too strong for you). One example, was dealing with 3 bandits with a low level character, and i managed to draw one away at a time, and lure them into the front of a cave of a shadowbeast(big mumma!), who killed them for me ;0)
It offers a great story, location, varied guilds to side/work with(Thieves/Magic/Army/Mercs etc) & the voice acting is top notch(although G3 voices sound better imo).Definate replayability as usual, with the varied builds & guilds to join. I reccomend this for any RPG'ers collection.
