Just got back from my trip to the Washington DC area. I stuck with the plan and brought my Switch and my new Anbernic RG40XX H. I kept the latter in my pocket throughout the trip and it worked out really well. I had several chances to pull it out and play #FinalFantasyIX which was great. Finally got through Ipsen's Castle and made it to Terra!
During the 8-ish hours of total plane time and a couple other occasions in between, I played #AstralChain on my Switch. I really struggled with a boss fight on the plane ride there, but it was a good challenge as it made me better understand the mechanics of the battle system (which I love).
Managed to get through that and then got stuck at a motorcycle sequence. After countless attempts, I decided to lower the difficulty level at the beginning of the plane ride home, which allowed me to finish File 9. Afterwards I realized that I haven't upgraded my legions in a very long time so I was very underleveled, which explains the difficulties I was having.
I'm now deep into File 10 and have been appreciating how awesome this game is. Very balanced and varied gameplay, great performance, and it even looks good when the resolution drops.
