Turn concession on much sooner.

[DrWreck]

Games are over well before 50% terraforming progression. I have a limited amount of free time in life, I do not want to waste it on LITERALLY AN HOUR(some players are very, very, very slow) of juicing TR just to concede.

Message the opponent your intention to concede, sell all your cards, and do nothing but Standard Projects.

If your opponent is crushing you that badly most of them will get this as a clear signal to concede at 50 and will help you out.

Did that, it still took 20 minutes.

You should concider not to play board games online then. Do it irl or play solo games. Better use of rare free time, probably more socialising, definitly more independent and for sure better for your mental health.

Hence "most people". Some just don't get it. Or aren't experienced enough to.
