you can get a cheap set of accessories off ebay. that includes a glass screen protector, carry case and i can't remember what else is included for like £7. whereas the orzly screen protector on it's own is like £8.
i got the orzly grip case though at £11 it makes it much better to use on the go and protects the console too.
if you are using docked mainly then get a LAN adapter £13 on amazon for usb 3.0 version don't buy official version it's a rip off. in fact a lot of official products are rip offs including the controllers.
if you have a ps4 or xbox one you can use their controllers (only 1 though) using an 8bitdo dongle i linked to it a page or two back.
get snipperclips, death squared, rogue aces, soccer slammers there are a ton of cheap games less than £10 worth buying.
Thanks mate. That's really useful info
