The elephant in the room here is TCG Card Shop Simulator.
This game is essentially (no disrespect intended to the dev) a carbon-copy of it, but with Hotwheels instead of Pokemon cards.

It has the shop-sim gameplay loop of buying products / stocking / pricing / and selling them,
the addicting loot-box-opening of your own products,
the tables that customers rent to play with your products,
if you've played one you've played both.

With that said, TCG has had a lot more time in development, so you're not going to see as much completion and polish with Supercar Collection Sim.

Some things I'd like to see in the future;

>More variation in customers.
Not just in appearance, but also in budget and taste.
Right now, once you've unlocked a higher tier of product, you can just abandon the previous tier altogether with no penalty.
This is nice in the game's current state, because there's no employees that have the capability of stocking your shelves for you- and buying / restocking a ton of different products becomes really time-consuming and tedious if you have more than a couple varieties on your shelves,
But in the future once we have employees to automate some of that, it'd be nice to have a reason to have more than 2 products in the store.

>More visual options for the store.
I'd like to have different textures and styles to buy for the floor / ceiling / walls / lighting.
Maybe even some different visual options for the shelves and tables themselves.
It'd be cool to have a store that looks a little more unique than the "wood floor / white wall" setup that you see in every one of these games.

>Less tedious stocking.
Specifically for the racks where you sell individual cars.
When you've got a rack that holds dozens of cars, it'd be nice to be able to "Hold Shift to Continuously Place" when you're pulling from a stack of 10+ of the same car.
Right now, it's really jarring going back and forth from stocking to the full-screen "Select a Car" menu when you're doing it repeatedly for minutes on end.
All of my other issues with stocking will hopefully be solved when more employee-types are introduced in the future.

All in all, considering it's an early-access game that just launched, and I have yet to encounter a bug, I'd absolutely recommend the game if you're looking for something similar to TCG Card Shop Simulator but with a different theme.

Really enjoying this game. Just a couple tweaks I'd like to see:

Battling customers should be easier. Nothing like seeing a few people at tables, and seeing that they all have ♥♥♥♥♥♥♥ cars, only to see them battle another NPC that has the good cars. Not even allowing you a chance to challenge the good cars.

Any chances for tournaments? Scheduled matches for good cars? Im tired of battling $1.91 cars with my $2000 beast.

Stats tracking - I would like a better way to see what Ive opened. The achievement of 'open a 1,000" is ok, but I have to be at least 5k deep on the top series. But I have no clue.

what are the odds on the different rarities? 1 in 3,000 on red? who knows?

wow just wow. as of now the game is new but already has everything for a great game. the game is as good as it looks. the devs have already added the communities top 2 ideas and im ♥♥♥♥♥♥♥ addicted. i never play games like this but have always had my respect for them. this one really hits home. what really grabbed me is the cars. all other shop games are boring and lame. this one actually consists of items i care about. really good. well made. attentive devs. strong early on and still has very high potential for more.
