I appreciate this is more a dilemma for some. In your case it sounds like the pricing in your country could be problematic.
Me, I was always going to buy the new Nintendo console. Yea some are certainly considered better than others but don't they all have great games?
Anyways, when I play games on Steam I get a bit overly obsessive about tweaking the graphics settings / resolution and either way the frame rate tends to suffer.
(I don't even think my laptop is good for gaming anymore. Still play Towerfall, but last big 3D games were Portal 2 and Psychonauts... years ago.)
Back to you, TC. You don't plan on owning an Xbox or PS4, but own a Wii U. You obviously like your Nintendo games (like me). Even if the Switch costs a little more, you'll likely find a way to squeeze it in your budget eventually, right? I think you're getting a Switch
