No, not actually tried it as every game I've ever played has always been from the start. Tonight I might give it a try, start a new game in the Nano era, see what happens@Argroww U started a Game in the Trans era? and u could play it?
However I know that in V42 or possibly one of the older versions I have been able to progress much further with higher amounts of money in the "bank". A rare CTD might happen, but usually not repeatable.
@Thunderbrd I'll confess to being surprised that the later eras haven't been playtested much and thus may not work as intended given how long the mod has been around for. On the other hand irrelevant of how powerful my laptop is turn speed by those eras is regularly painfully slow which suggests computing power makes little difference and playtesting in that stage of the game would be a nightmare.
Never finished a game irrelevant of mod version as historically by the time I was getting close a new official version was released and I started again to see what was added.
Something I was puzzled over that changed in V43 I think. I'm sure older versions forced you to build probes and such to be able to build the space themed wonders, but now as long as I meet other pre-reqs I can build them, making several of the early space units kinda useless. And those early space units often served to make the gap between early space exploration and being able to build cislunar and lunar settlements less stretched.
The annoying thing about this bug that's halted my current game is the AI was fairly close to being able to make cislunar+ settlements and I was curious to see how it would handle it.
