Splinter Cell I got completely addicted to the sims (original) when I picked it up. I never got into it past that first purchase (I think it was the base game with the first two or three expansions included) as my addiction wore off. Mel was the opposite. Sim's Expansions kept her happy for years of birthday and chrismas presents.
I got addicted to the Sims 2 once they released that for Free over on Origin last year. I sat on that game for up to 16 hours at a time. I adored it. But as with the first game, I got my fill, and doubt I'll ever go back.
The main thing I'll likely (eventually) get around to the sims 3 for is the open world. As that is apparently removed in the sims 4 I have no interest at all. Unless of course I get that one for free as a complete game when the sims 7 is about to come out, or something.
I put over 300 hours each into the two The Sims 3 games on xbox. They are quite different to the PC versions. Personally I consider them superior as they seem to have a point. I like knowing there is an end game to reach eventually, rather than.. just petering out due to lack of anything new to try.
