In my experience, the amount of techs has massively increased, which is leading to the situation where lower tier techs become increasingly rare over time, which can lead to weird holes in your tech tree.
Some examples:
The year is 2290. My research isn't great, but it's passable. I have skipped the robots tech two times, since I didn't intend to build them. However, the last time the tech showed up was 40 years ago (or so) and I'd really like to take the Flesh is Weak. I am considering just console commanding myself the techs, because Oh My Shroud.
Different game:
The year is 2305. My most recent society tech was Gene Tailoring (FINALLY). The one before that was Eco Simulation (+10% Farmer output) a Tier 1 tech that can be in the first draw of cards. I STILL do not have the planetary building for boosting Farmer output, because I hadn't rolled Eco Simulation in decades.
Lower tier techs need their weights massively increased, if they are the requirement for other important techs. Things like +10% Pop Growth can be left as they are. They don't lead to important gameplay-changing bonuses, they are simply numerical boosts.
