I’m a huge fan of Borderlands so would recommend that and I’m also a huge fan of Halo, the Master Cheif Collection is an absolute bargain considering what you get. Your brother with the Xbox will need to get Game Pass of some sort to join in for any games that are not free to play. Halo Infinite is free to play and has a PvE game mode, if that tickles your fancy.
I don’t buy it. PC and Nintendo are more than enough competition. Sony has always been this way and they always will be. Company culture doesn’t change, Nintendo will always be letigious, Microsoft will always seek acquisitions and Sony will always be arrogant.
As good as the Steam Deck is a smaller option would be nice. This sector of the industry is still trying to find the ideal form factor.
If the lite model looked more like a Steam Deck and was priced more like a Steam Deck it might be a more tempting option.

That initial screen shot is giving me serious Facing Worlds from Unreal Tournament vibes.
