Hi.
What is the point of doing research? Getting more powerful weapons? Faster engines? No. The whole point is economics. It's either to generate more money or lower the cost of a product. Research is a project, and like all projects, you have to take into calculation cost vs benefice to determine if it is worthwhile.
However, in this game, the amount of money and time you have to invest to in building the labs, paying the upkeep, invest the money to generate research points is so big that there is no way i see for it to be worth doing it when you consider that you may replace these installations with factories or farms/economic buildings.
Did i say that technology is worthless? Not at all. I'm just saying that researching them is not efficient. Buy them, take them by force.
It's strange for me to say this, because in all other 5x games, i love doing research. My suggestion? The creator of the game should revise the benefits and cost of the technologies in the game.
Let me know what you think.
