When I say that today is more about 'realistic' gaming I mean that people want to play games about controlling squads of soldiers or racing in F1 cars, rather than flying a spaceship against waves of enemies or bouncing round a multi-coloured platform world as it often was in the Amiga days.
To complain about modern games all being the same is to ignore two things:
1. Games need to sell and the suits will always pick something that's worked before over a new idea.
2. If you don't think that Amiga games were about copying ideas, then you haven't played enough Amiga games. If I had a dime for every identical Amiga shoot-'em-up or platform game, then I'd be rich!
