In my opinion, the Ducky would be a great start.
they are probably not options for you because of the high cost of shipping, but my top recommendations for gamers would be pure (pro), race (2) and poker (2).
they come in many options (backlit with abs or non-backlit with pbt, pcb-mounted or plate-mounted, choice in cherry mx type..), they are small and in my opinion have everything a gamer would need.
which one i'd ultimately recommend only depends on how often you use the F-row, arrow keys and home/end/pgup/pgdn.
of course, if you really don't care for the extra space it takes, TKL brings many more options to the list.
personally i just absolutely love the flexibility a small keyboard gives you, when it comes to using desk space. depending on what i'm doing, i can easily move my keyboard and mouse around with very little restriction.
I'll check the shipping of those later today and yeah, reason I wanna buy a TKL is because of how little room it takes up on your desk, compared to a full form factor.. So an even smaller might not be stupid
I hesitate to recommend a 60% or 75% board for a number of reasons.
1. If the games you play use the F-keys, a 60% will be awkward / slow to use (you have to press the Fn button to access them)
2. If you want / need dedicated arrow keys or edit cluster (PgUp, PgDn, Home, End, Ins, Del)
3. Getting used to the layouts and deciding which layout is best for YOU. Some layouts have really small shift keys and keys in unfamiliar places which can take a lot of getting used to (KBT Pure Pro, Race, Keycool 84, etc.). This takes some time and effort to research and sometimes you won't really know until you actually try a particular layout.
4. Many of them use unusual layouts and it's hard to find keycap sets to fit. An exception to this is the Poker 2 which has standard ANSI layout.
I have a KBT Pure 60% board and, though I love it and think the Fn layer is definitely the best for me and the type of work I do, I am still getting used to it and am more comfortable on a TKL. I do a lot of text editing, selecting and moving blocks of text, etc. and holding shift while using arrow and edit keys on a Fn layer and then using copy / cut / paste shortcuts while moving the cursor again with arrows on a Fn layer takes some getting used to. I did sacrifice keycap compatibility a little (the right shift is a non standard size) to get the Fn layer that I like the most, but have found some awesome keycap sets on GH that fit (usually if they offer what is called a Tsangan kit they will have the 1.75x right shift that I need). Also the biggest size jump horizontally is from a full size to TKL.
So....
If you need F keys and arrow keys on the main layer and don't want a weird layout (or extra layers to deal with), go with TKL.
If you need F keys and arrow keys on the main layer, but are okay with a weird layout, have a look at the KBT Race, Keycool 84 and Noppoo Choc Mini. Some gamers really like these.
If you need arrow keys on the main layer, but not F keys, look at the Leopold FC660M (I quite like this layout. ANSI TKL keycap sets fit except for the right shift.
These are usually available with Clear switches, too.), Filco Minila, Tex Beetle and KBT Pure Pro.
If you don't need arrows or F keys on the main layer, but want a standard layout, there's the Poker 2.
If you don't need arrows or F keys on the main layer and don't mind an odd layout, there's the original KBT Pure (although these are getting rare)
Then there's the GH60 which can be configured for the 3 main 60% sized layouts (Poker 2, Pure, Pure Pro) and there are also some custom boards with either Poker or Pure layouts.
Some of the 60% boards (and a number of TKLs) are available on Amazon.co.uk and at least in Finland the shipping is cheap and I don't pay customs since it is inside EU. Not sure how it is in Norway, due to not being part of the financial Union, but still at least Schengen state...
The rabbit hole goes deep, but at least you're in good company

I am actually also a relative noob in the keyboard world (got my first mechanical last year), but have learnt SO much from the other members here on GH.
I have since spent far too much money on keycaps, though.... <sigh>
