I'm not a huge fan of Kits, I didn't grab any of them so far. I am basically happy with my game, and I'm not so glad when EA force me to add lots of stuff (500 skin colors, 1400 window recolors, or what it was?) - details I never missed and would prefer adding as optional content. I'm now "looking forward to" added stuff to several old packs or even the general game lore - stuff I'm not focusing on at all after 7 years of developing my own game universe. I'd rather wish EA directed their resources towards new (optional) stuff in GPs and EPs. I can choose to not install patches with the old stuff, but suddenly they will release a pack that I want, meaning I will be forced the flood of (to me) useless adjustments to old stuff. It's a problem that EA sold me a base game to work with my old computer, then later they add to the base game until it will no longer run on my computer, even if I had not bought any packs. It just doesn't feel right to me and I wish I could have a tad more control on what to add to my own game.
That said, I'm pretty sure we will get more big DLC in the future. IIRC they have confirmed they are working on horses, and that they are separating babies from cribs, and there might be a few more features they said they were looking into long ago, too. So, I'm pretty sure we will get more good and desired stuff, so I'm hanging on.
I'm personally hoping for a French world, although I'm not focusing a lot on romantic stuff, it could include nectar making and I've visited France in RL so many times that I would surely enjoy a related location in my game. It would also be the perfect location to expand my nobility a little, perhaps I'd finally include Royals to my mix. I also want Hotels, although I already have a few hotels in my game and I won't mind pretending they work satisfyingly. I play rotationally so I don't really think I could benefit fully from EA hotels anyway, but the concept might include some nifty features to be used elsewhere (cabaret stage, casino/billiard, multiple community lot tags per lot, served reception desks). I'm not enough into occults to wish for more of them in my game, but if zombies or werewolves come with the French world, I'll find a way to embrace them (a werewolf pet for Judith Ward?).
I'm disappointed if we don't get another major pack this year, because I know I won't grab a kit with 12 outfits. But I'm clinging to the hope that they did not really confirm that there will be NO new EP/GP this year. Awaiting any hints during the Inside stream next week :)
