Roblox is full of different kinds of games, right? Why don’t you find out the kinds of games he likes there and find recommendations based on that? It’s a start at least. I would imagine most of the Roblox games are clones of better games anyway.
Honestly, why would we need a Stardew Valley 2? There’s so many harvest moon games but are they really anything more than small iterations? Not to mention those have been garbage since the IP was basically stolen from the original developers.
And then you’ve got absolute mad men like Concerned Ape making stardew valley 10 times better with free updates for years and years. Showing these money hungry companies how it’s done.
I will say once more. Do not preorder video games. It could be shit, it could be buggy, but what it won’t do is run out of copies. Wait until the reviews are out, or even a bit after it launches if you can. If you’re anything like me you have hundreds of games you haven’t played yet so what’s an hour or a day in the grand scheme of things.
Reminder: do not pre-order video games. There is not a limited stock of bits and Bethesda will absolutely fuck up and fix bugs in a month. You can wait until you know it’s good or even for a sale.
