For sheer versatility you can’t beat PC, so that is going to have to be my choice. Having flexibility between KB+M and controller, having access to mods and tweaks and (typically) having a wider array of graphics/performance options to tailor to your preferences makes for an unbeatable package.
That being said (and it pains me to say this given my distaste for Nintendo), I absolutely loved the 3DS. The dual screens were cool, it had good ergonomics for me and a nice weight in your hands and there was something very satisfying in the mechanics of flipping it open or listening to the click as you slam it shut. It’s just a really nice device to use.
I’ve been mainlining Esports Godfather, which is the surprise hit of the year for me so far. The title is nonsensical and on the surface it looks like it can’t be good, but it’s been so much fun.
It’s a MOBA-themed sort of deckbuilder/autobattler/management game - which sounds like a hot mess but plays so much better than you’d think. At least after you get over the initial information overload.
I wish the AI was a little smarter, but even with the game being a touch too easy it’s incredible how much fun it is. Loads of cards and heroes to build synergies with and rotating version rulesets keeping things fresh even within a single run.
At just €16 on Steam I’d easily recommend it to anyone with an interest in the genre, and there is even a free demo that covers the first couple hours of a run.
