It's taken 15 years on/off AE to get the #1 Valuation spot but finally did it in the April-July 2020 round of S1. With lockdown and being able to work without seeing people face-to-face, I finally had the time and energy to go all-out.
Having joined AE in 2005, I had managed to quickly grasp the meta of producing tons of DOP. Unfortunately, the prevalence of bugs in AE2 meant non-stop maintenance which was an impossible slog. This left such a bitter feeling that I did not return to AE until several years after reading Yuxi's mass e-mail about the improved AE3.
AE3 was definitely a huge improvement in terms of bug reduction and functionality. It is extremely easy to search, create and maintain routes compared to AE2 and other competitors. However some bugs still remain, such as:
1. Anyone swapping aircraft messes up connecting demand and needs a route reset.
2. In S1, there's a way of creating many terminals in a one terminal world.
Still, better than having to reset one-way routes every 59 minutes past the hour in the old days. Or people magically creating 5 extra gates at a 0 gate available airport by simply creating a new airline.
I can now rest easy with this game.
