Might & Magic series

<-- Major fan of M&M 3-5.
I got MM3 from my cousin and my PC was hardly fast enough to play it, yet, I've spend countless hours in the game. It was just such a HUGE gameworld. So many spells, so many enemies, so many quests. I enjoyed that alot.

M&M4 felt like a completly new game as I got it, and it needed SOOO much HD space. But it was worth it.
The whole atmosphere of Clouds of Xeen was breath taking. You got punched right into a magical world, through an incredible intro, and had to find your way around. Also, if you played 3, you wondered how the technology at the end would fit in. There was a revelation at the end of MM3 that told you how the Isles of Terra were created by some spacefaring race, and its protector went insane (endboss).

I was very happy about how Clouds added a bitter amount of technology and how it well it mixed with the general fantasy theme of the game.
Later then we got Darkside of Xeen, where the creators once more proved they had an outstanding way to use colors to make this world feel different from most others RPG. It wasn't plain. It was very bright, with lots of orange, violet and other strong colors.

I never got into the later games. I think I felt the new designs and engine didn't work with the former games and how they were presented.
I'd pay a lot to play a game in vain of MM3-5 again

Jam it back in, in the dark.
