Overall the game can be fun and there's potential. I think it could make it to Steam of nicely polished.
Make a small tutorial.
Contract negotiations. That would be a good deal. Like opening a negotiation with a company. How many factories you could assign to them, price and other. Imagine more like FIFA contract negotiations (not exactly like that, but you get the idea). Also, contracts starts at Jan 1st. Not really realistic, because, sometimes, console companies and computer companies are hungry for the chips. So, why waiting when a chip manufacturer can deliver?
The "Inspector" tab is awesome. Why can't we compare to other manufacturers? Just make a "Compare" button that puts chips next to each other (more like GSM Arena does).
Just like in the first game, researching more "core clock" doesn't make any sense. The core clock e.g. My Ryzen 5700X3D isn't 4GHz because AMD is not putting more effort in researching better clock speeds. It's a thermal limit, which is in the game already. The clock speed should be thermal limited and not research limited. That would be realistic.
CPU Core's - While the fact that research was needed to realize that we can put more than 1 core / chip it's a true fact, anything past that is not ... realistic. Research should be something like Multiple core's unlocking (maybe 3 stages ; 2 cores; 4 cores; all cores). Usually the amount of cores put into a system is defined by power consumption and thermal limits. Also, Multithreading could be a tech. (Intel Hyperthreading ; AMD SMT)
CPU Cache - Don't limit it by research. It doesn't make much sense doing it so. Most of the times, the limits are price and size (e.g. Does this much Cache fit into the chip?) so why having a research limited Caching System?
Make sure to implement ASAP a Bank and Marketing Tabs. Even basic ones are much better than nothing.
