Well most new games are either something already done since 20 years like Far Cry and Assassin’s Creed or something bugged with the need to wait at least 3 patches to be hable to play it with limited problems or being first a skin store then secondary a game with update being mostly limited to cosmetics
Get them a Vsmile (it’s not Nintendo)
But seriously it depend of multiple thing, if it’s for playing online, must look at the price of the subscription (don’t know how it’s on Xbox, but on Playstatio basically it’s minimum 70€ for online and three game he probably never gonna play)
If it’s for playing with friends, he “need” the same console (or same company console like PS5/PS4)
If it’s offline, maybe playstation is better cause there is lot of offline games, Ratchet and Clank, Sackboy Big Adventure, Patapon, Gravity Rush, Medievil, Knack, Tearaway and depending what games you accept them to play (so you need to look at them before cause there is mostly blood present, but in the exemple i give, if you let them watch the first three Indiana Jones it’s probably not a problem), there is Uncharted, Infamous, Final Fantasy VII, Spider-Man or Ghost of Tsushima
And all of theses exemples can’t be played on Xbox or Switch (generally), cause there is also multiplateform games like A Hat in Time, Asssasin’s Creed, Rayman Legends (this one is perfect), Lego games, Psychonauts, Tomb Raider, Little Nightmare and lot of other
To resume, if the friends have a Xbox to play online, Xbox seem the best choice (after i know nothing about xbox, all i know is that Halo is THE game to play on Xbox)
For the rest it seem Playstation is better
Releasing the game BEFORE selling season pass and DLC (and also stop with FOMO elements)
