Pretty decent update really, QoL improvements for management, new theme (snow map & winter themed items), new shops & rides, and just... BUMPERCARS!!
I do wish they'd add stalls though, perhaps more commonly associated with fairs but certainly not uncommon in parks, especially those where you're paying per-ride, compared to just a gate fee. I think they'd work well as 1x2 or 2x2 area boxes like the shops are 1x1, and let us theme them rather than them having their own exterior.
One thing that does kinda bug me about the rides is that they're pretty distinct in what sort of theme they suit, the whirly-rig feels pretty specific to a pirate area if you're building themed districts, and theres a few very sci-fi orientated rides too. Its not like a pirate ship, where you cant really dress it up as western or something, and yet rides like the whirly-rig could have 2-4 skins that make them more neutral or orientated to specific themes like princess/fantasy, western, sci-fi etc. Same story with coaster cars, but its the flat rides i think feel like they're more restrictive.
As for CPU issues, i havent actually noticed, but being honest im pretty sure i have the fps locked to either 20 or 30fps (edit - 30, cant remember whats locked to 20fps.. Ark
why fight it hehe). When it comes to management games and stuff thats rather leisurely, i just dont see the benefit, i guess im fortunate it doesnt hit me like it seems to hit others, and ive never actually monitored what its hammering (if anything) as ive not seen anything to make me wonder.
