“[h1]TL;DR[/h1] 9/10: Dang making money and hoarding real properties, cars, and artwork is awesome. I also love that assistant Amy. The new girl Sae (the bartender) is pretty good-looking, too. This game really captures…”
“I had to raise 5 billion yen in 3 months and instead of selling some assets I gambled for a month straight on the weekends and turned a failing company around.”
“Recommended 👍 Stonks 9800 is an absolute gem for anyone who loves strategy, finance sims, or that nostalgic late-90s PC aesthetic. The game perfectly captures the chaotic energy of market speculation while still…”

“I was expecting to play for a few minutes at most, then I became a billionaire and played for over 10 hours. There is a lot of charm and events happening one after another, the design is very simple and uniform but no…”
“Disregard the meme name and banner, this is actually a great, high effort, deep game that is clearly a labor of love. That's a good economy simulator, life sim and loads of mini games (not my favourite part but they're…”

“This game had a more than enough content to justify its price many, many updates ago. At this point, it’s pretty amazing how much has gone into it, as it almost solves the classic problem in any of these games, that…”

“Almost 40 hours in and its still not the full game. Worth every penny.”

“It has all of those elements from mobile life sim games (bitlife, etc.) but makes them have actual depth and interactivity with each other. filled with lots of little things to keep you busy, from fishing to arcade…”
“I know were all here to goon, but it’s unironically a really fun game. The progression system with unlocking new cell types, goblins, and special characters is very addictive and i hope the dev makes a dlc in the future…”
“Start poor, invest here and there, then by chance set up an illegal drug company by meeting a person at the bar, said company gets listed in the market and proceeds to climb from 9k to 100k before i sell all my shares…”

“STONK-9800 is a fantastic game. Even in early access there is a lot to do and the chaotic ways you can get an edge or make money keep the game interesting. I am hoping more content around dating is added. Having more…”

“9/10, buy and play this game to know what is trading before doing your actual trading. The price is small for a game this deep, very worthy. I thought it will be another of those "business" related games and expected to…”
“First off let me say, i love this game. It's fantastic. BUT! i just want to make the dev aware that in the secret poker room, i just lost a game worth 400 shares because my opponent had 45 chips left, i had 700…”
