If we think 1 EP= 40e
I would wait sale since eps and gps are often 50% off and you could get 2-3 packs then and have more options and things to explore
I still feel like Seasons is most essential for me with EPs but its more so background thing making things more lively less so something with big amounts of stuff to explore
if you had two packs in sale you could then pick something more themey or activity based for the second option
or add couple gamepacks that interest you
or indeed with 50% off you could get 4 game packs for the ep price which does sound like more fun to me than just one ep
but then again I do like occults and they are often in GP so theres that :lol:
