After several Spore projects got cancelled, and we were juggling family/work life, we didn't have a lot of time/motivation to post a lot of news to the Spore site. So in 2013, SNW (SimsNetwork) merged sites with MySimsNetwork, SporeNetwork, SimCityNetwork and SNWgames. These sites all had their own front page, header, content etc. But because it was all technically one site, it was easier to maintain, and it all looked like it belonged to the same site (which it did, so that was good in a way).
It's not my favourite design ever. I quite liked it at the time for my Sims site, just not for the rest of my sites. Which was evident because I hardly updated the other sites anymore.
