Someone already made good comments, but let me add to it.
There is a class of games on steam we call shovelware. It means, games sold that are built on premade assets or bare minimum effort.
There are several things that make all shovelware titles similar:
- Fake reviews (look carefully, 90% of the reviews on all of them are purchased/phony)
- Overpriced (to make the discount appear generous, but really is not. The games should be sold at the discounted price in the first place)
- Very little content (Game has less than 1 hour of gameplay before you finish everything, even achievements)
- Premade assets (Either copy and pasted or remixed game from unity / unreal asset shops, google to find some examples)
- Almost zero development time (games released within days to weeks from each other, shows no effort)
You may wonder, when they have to pay valve 100$ to upload and sell their game why would they do it? Because when you live in a poor economy, the dollar is worth a lot, and printing keys for these games and selling them to bundle sites like DIG or russian lequeshops actually makes a profit. Not much, so that is why they keep making more of them after they reach their limit.
In recent years we see these overpriced games and suspect they were for exploit giveaway value, this is why SG started war on them making them all 0 CV, which these games are or are being added shortly.
I wouldn't buy them, but if you have to, look at DIG's website for pennies.
