I don't think you need our comments that much. This device is among the most well-received of its kind in the world. You can watch YouTube videos that talk about it in more detail if you want to be convinced.
It is generally a safe choice that will last many years and you will be able to apply it to every new phone. It is fully future-proof because it has "next-generation" buttons and sticks that are magnetic, so they won't show signs of malfunction or sticking. Its quality is similar to Xbox quality, since this company has made Xbox-approved consoles in the past.
It also has its own mobile app that can perform firmware updates on the device, meaning it will improve over time as well.
In my opinion, there is a small downside, but it's not a big issue; it's more of my personal opinion. The G8 accepts a type C connection, and there are Type C USB sticks. I thought I could have emulators and roms downloaded on the stick that I could connect to the console like a memory card and play the titles I want, but the port doesn't recognize anything beyond charging. A bit unfortunate, but it might just be my crazy need that no one else cares about, lol.
Also, many say that the G8's arrows feel a bit weird, which yes, they are a bit sensitive, but they don't cause any issues and many consoles have had something similar, so many of us are already familiar with them.
In some games, it can be a bit tricky to get it to work, but in 99% of cases, you can find the solution as long as you look into how to set it up (YouTube videos).
The G8 Galileo is a solid choice. You don't have to worry about anything. It is among the best in the world at what it does.
Now a tip: I would suggest that before you buy it, don't treat Skroutz as the only option. I had typed in Google for the console and in the end, I was able to get it for €72 including shipping and everything. Check if other options suit you, and in the end, if you prefer what Skroutz offers, THEN buy it from there. Skroutz usually has the best deals, but for this purchase, it’s worth looking around.
