I've still been playing Fire Emblem Engage in bursts, but don't think I played it this week - however, I think I'm on the last chapter now, so might finish it this weekend. Although there's still DLC chapters to do that I haven't looked at yet.
What I've actually been playing is Pokemon TCG Pocket. I played PTCG Online a bit just before it transitioned to PTCG Live, and then continued with PTCGL a bit after that, so I was already familiar with how battles work. So far, I'm pretty happy with PTCGP. It's a simplified version of the normal PTCG rules with custom cards without real-world equivalents. It is definitely more straightforwards, which is nice for doing quick battles but limits the types of interesting plays you can make. What I really appreciate is some kind of single-player mode (which they had in PTCGO but scrapped in PTCGL) with interesting challenges to do.
I'm not sure if a meta has emerged, but I feel that the online battles I've done are farily diverse it terms of the decks people use - I think there are more viable decks to use. In PTCGL, there were like 3 or 4 decks that everyone used, so that battles were really repetitive.
It's still early days for PTCGP, but I think it's a very well made game. Not something I'll play all year round, but might dip in every now and then.
Ah, I didn't see your edit to say you'd played it too. I'm not sure if it will appeal to a more hardcore player (I hadn't played any for at least a year prior), but yeah, I think it's pretty nice for newbies and more casual players. Some people will like just opening packs and might not bother with the battles.
One thing about PTCGL was that the app/PC client were really bloated, slow, and ran hot on my devices. The app for Pocket has great performance.
