I had a Vita and I loved it, it was incredible compared to the PSP and 3DS.
But the internal memory was a joke making the memory stick practically mandatory if you wanted to buy a game in the store, which being proprietary wouldn’t be an issue if it wasn’t expensive as hell.
The catalog of games was really small (at least in Europe, maybe in Japan wasn’t the case). I loved the few games I had but every time I tried to go to the store to see if anything interesting had come out I was disappointed.
The development platform for indies was a framework for mobile phone that was focused for Sony smartphones, so indie games couldn’t take full advantage of the console.
It felt like Sony abandoned the console too quickly and let it agonise.
I still complain about bugs, but instead of blaming devs or qa I blame managerial positions and stakeholders.
Huge bug in game exists:
Non dev gamers: “How didn’t they catch this blatant issue?”
Dev gamers: “How many times the issue was addressed just to be told to work on something else with greater priority like <random stupid thing>?”
