I remember watching my sister play MySims on the Wii a long time ago, played a few times myself as well. It was enjoyable and honestly the nostalgia factor I can see making it worth revisiting
I absolutely LOVED mysims on the DS - it was quite possibly my favourite game for ages, and I even rebought it when I was a bit older and had lost my original copy just because i missed playing it that much. now with all the hype over the switch port i've considered rebuying it again - I never realised that the wii version was different to the DS version, so the port won't be as nostalgic to me as I initially thought it would be. I'm still really excited to buy it though! I haven't bought a new switch game in ages and I think this will be the perfect cozy game to get me through the depressing winter months as a uni student lol
I've only played MySims for the Wii. I got it for Christmas in 2007, I think, and started playing it but ended up quickly losing interest in it. I wouldn't actually pick it up and finish it until over a decade later. It's fine, but it's just not my kind of game, honestly, so I can't really see myself picking up any other releases of it.
