Thank you, its good to see some familiar faces. Games, I guess exclusives are the big one. I play a little of everything so id take any suggestions.
Those San Disk cards are great and Amazon can get one shipped to you in a matter of 2-3 days depending on your location.
You should take a look at some of the free offerings on the Switch, Paladins (overwatch clone), Fortnite, Arena of Valor (League of legends clone), Warframe (Destiny style game) are all free2play and really worth a look on the Switch, if you don't have a SD card though leave off warframe since that's around 17GB to download.
Paladins is fantastic on Switch though, crossplay allowed with the X1 so there's always games up at any time of night.
In terms of things I would recommend for the system I would at least advise you have a US (in alaska for zero sales tax) and EU Eshop accounts, you can put both on the system and buy games in either account and play them on your main account, very few titles have any problems with this and I would only ever consider a region when it comes to buying games which might be online focused in my home region. The reason for the 2 account shops is the eshops getting different games going on sale and for different prices, this last week for example Superbeat Xonic was dropped from 40>26 in EU but in US it was dropped from 40 down to a $1 97% off, helps to shop around.
In terms of how much fun you could get from the free offerings alone...
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
