I still like Morrowind but Might and Magic definetely has a charm that MW does not. Playing MW I often get the feeling that I have seen this before. I am not talking about the main quests or faction quests but about all other - most of the caves are empty and contain poor treasure, the huge landmass is almost empty, the miscellaneous quests mostly look like Copy and Paste.My favourite quest series in Morrowind GotY was building my own mining colony Ravenrock on island Soltsheim. This is something I really missed in MM games - to participate in events to build a whole town or at least my own home. In MM7 it was done partly - renovation of a castle, later upgrading it but nothing more. Also in Morrowind you can build your own stronghold (and choose from 3!) but still it was not what I wanted.
I like MM because all of the events are linked - the next episode tells about next events. The game is not too great in size, has a good humour and a great doze of adventuring feel - that's Might and Magic.
