Lehesu, if you can make 1300+ posts here and forget about RTW, then I suspect it is not for you. It sounds like you a case of irreconcilable differences and you have moved on - turning back now might just cause you pain.

For what it's worth, I hated the demo too but had faith that RTW would not ditch the things that made its predecessors such fun and found my faith justified. I can only speak from a SP point of view, but if people like STW and MTW, I can't imagine them disliking RTW. They are just obviously the same beast at heart - don't listen to that "RTW is for the RTS crowd" rubbish. However, I know that in fact some people do see the differences as sufficiently large to change their attitude to the game. If the demo put you off so much, you might be one of those people.

To make an analogy between the Total War games and potential romantic partners, I would offer the following:

STW is like some kooky person you meet, hits you right out of left field with their zest, idiosyncracies and character. Funny, innovative, stylish and wonderfully unique. Ultimately, you may find their mannerisms become repetitive and their limitations start to grate, but you will always remember them with affection.

MTW is like the rather plain person you sit down next to and unexpectedly find yourself talking to well into the early hours. Outwardly rather bland and characterless, inwardly deep, engrossing and compelling. This is the one you could settle down with and probably should.

RTW is the absurdly good-looking one who turns everyone's heads and knows it. Smooth, urbane and graceful, this one can effortlessly dazzle and charm. However, for some strange reason, things might feel a little too easy and when away from them, in the quiet of the night, you wonder if they are just a little too shallow.
