Having not played The sims since the original on PC, I wasn't massively sure what to expect on this console port of the most recent copy.
Though I haven't played the PC version, I would assume its fair to say any game of this platform are always more accessible and better played through a good PC and so a 4* rating seems more plausible.
However the console version is more than playable and very enjoyable once you get to grasps with it. I would like to suggest this game is more like marmite, you will either love or hate it. It very much depends on the type and style of gaming you enjoy. I love fast action paced games, however still enjoy a slower game which is quite light hearted from time to time to break my gaming genres up.
Don't get me wrong this game offer high levels of dynamics on how to play it, you can be as realistic or as creative as you like, enflicting evil or real life situations at your peril if you want, so the game can be whatever you make it.
But if you purely like the gameplay of games such as COD etc, this may not be the game for you, for those who like something a little different to break away from the standard shooting, driving etc platforms now and again, I would recommend this game and suggest you make it your own and tailor its gameplay to how you view gaming most enjoyable.
