I have played boundless for over 400 hours, but i rarely play it now. I only refill portals in PG, hunt for oort stones from time to time and check city progress.
Am I bored? Hmm, not really. I just don't have any plots left. All out of my 170 plots are used on roads in Pixelgate. Currently i can't grind more because progress is so slow that it would take me like 2 hours to grind 1 plot.
I would like to build many, many structures, but atm the only way to do that is to start another community project I feel like the game wants me to stop play it because i can no longer progress/build more stuff. Just look at forums and check how many people GIVE AWAY their houses because they want to start a new project somewhere else.
My suggestion is to allow players to gain infinite amount of plots as they play more and more. More engaged players = more plots they get through daily/weekly quests (constant amount).
Please consider this. It's important, because at 1.0 i would want to play as a builder named Karokendo, not as 10 different characters (each with 100 plots) because that would be the only way to gain more plots.
