I usually don't play with mods or CC until a game is done being developed - then I determine what - if any mods and CC my game could use. Like I have tons of CC for Sims 2 and a couple mods - but Sims 3 I use no CC or mods as I fixed what ever needed fixing myself to stop issues - and definitely didn't need any content - I own all packs and the whole store - so my game lacks nothing and has no issues.
Sims 4 - well when it is done being developed then I will see what, if anything it needs.
