I struggle to get decent gaming sessions in these days as well, other stuff just gets in the way
Most I’ve done recently was when Let’s Go came out and I put about 8 hours into on the Saturday, since then its been an hour or two here and there.
Edit, caught Zapdos bringing my dex up to 100 caught!
Still need to catch a few more before I do the 8th gym. Farfetched, Scyther, Dratini (although I’ve yet to even see one of those yet), Machop (and Machoke( plus a few more evo’s like Parasect, Golduck, Hypno, Eevee and its 3 evolutions. Can’t actually recall the last time I actively focused on filling out my dex, normally I just play it then restart it after banking all my Pokémon.
