So yeah, I tried the Brookheights mod and I have to say I'm a little disappointed. I think it's really great that a Modder tried to create an open world, but this didn't feel like an open world, more like one big lot, which is what it is. I know this is still the beta but i don't really know how much more the creator can improve it. The world is a little buggy, which is to be expected, as i ordered drinks and food at the bar and never received anything although they took my money. The car aspect is alright, except that if you place your car when your in a rabbit hole, it's lost forever and you have to buy another one. As it's a big lot, the NPC workers tend to go off and do other things so places like the cafe are not playable as the barista is never around.
I liked that you could go to the gym or your hotel and just Zoom in, but there are quite a few rabbit holes that i believe should not be in an open world. Also i don't think this mod plays well with other mods, as my game crashed when i first tried to play, and i decided to just take them all out. In terms of gameplay, i don't think this mod adds anything really and found myself really bored. Once you get over the hype you realise it's a bit more restrictive than it initially seems. I think this creator probably should have focused on doing a mod for hotels or something as i liked the hotel aspect of this mod.
Also if you don't have a really good graphics card i don't think you will be able to play this mod well. The city is really lovely, i didn't have any issues and i was able to appreciate the build of the world, but i play my game on ultra. I do recommend people give the mod a try, mostly because of all the work that went into it, but i don't really see my self playing it again, unless something drastic changes or has been added.
Sorry for the long review, but i feel that the sims team should be ashamed that a modder had to do all of this work, and we're six years into this boring game. God where is the sims 5???
