If I may suggest anything, give Just Cause 3 a try. I my self love cRPGs, jRPGs, classic RPGs, and RTS, and .. I have really no idea why I tried JC3, no one recommended it to me, I think I saw a screenshot of one of the islands somewhere and something clicked. The gameplay.. well, your avatar in the game regenerates like crazy, making you almost invicible. Got a problem? Hide somewhere behind a lamppost for 20 seconds, and off you go. At first I was really disappointed. I don't like that kind of "superpowers", and almost stopped playing. But then, some I catched some humour in the dialogues, and I gave it second chance. A moment later, when I understood it's not meant to be a real challenge, almost not meant to be following the "story", and that's all about having fun destroying enemy bases in the most creative way (like, fly a plane right into their fuel storages, etc), and adding to that my beloved open-world design that becomes available really soon after some initial intro missions (though I don't recommend going to the north-most island without having your gear fully unlocked/upgraded, it takes a few initial missions) -- oh well, I wanted to make that brief, sorry :)

Ah, I found it. Probably the best summary of the game for me is the old wallpaper:
