I know that a lot of games are coop online or with different systems, but we wanted to play together, in the same house, and didn't want to have to buy two seperate games and systems. Which is why we've largely shied away from PC gaming, because even the lan versions of games usually require you to have two different serial numbers, as we've recently discovered with Neverwinter Nights.
I played as the archon Anjali and my husband was the gunwoman, Katarina.
We played every chance we got until we beat it, and once we give it a rest, we're interested in seeing if there are some alternate endings.
This and Dark Alliance 2 were probably my favorites. These were released on PS2 and XBOX. It was a lot of dungeon crawling and hack and slash, but I loved the quests, the leveling up and playing something together. I as usual, was a magician. DA2 was fun because of the customization and gems with the weapons.
While this and Return to Arms are set in the same universe as Baldur's Gate, and the game play is similar, I thought I'd mention them seperately because I played both groups at different times.
We enjoyed the gameplay and the set up well enough but didn't like the ending. I'd still recommend it though. This, I do believe was a PS3 exclusive.
