Pokemon games. I played all the games up to the Gameboy Advanced, missed the DS and have purchased all of the switch games. My wife and I actually buy both versions of each game so we can trade and battle.
I liked the open world and encountered very few bugs despite all the reviews talking about the bugs. The battles are the same as any mainline pokemon game for the most part. The entire game is in an open world I found very enjoyable to explore, personally. In sword I was a little disappointed by the very sectioned-off open world segments. The fact that the missions are laid out in a non-linear do-it-in-whatever-order style is quite nice as well, IMO.
