Following my departure of playing CS:GO and most of its communities I needed something new to fill my spare time, of which I have a lot of. For a while now I've been watching gameplay of osu, considering its target audience, it was only a natural transition.
I began playing opsu, an open source osu client written in Java. Opsu is a great alternative to the (currently) Windows only osu, however, I eventually wanted to experience the real deal.
Following a fantastic tutorial for installing osu on Linux via WINE by Francesco149 I was able to experince the real deal. Comparing opsu to osu is unfair, however differences are very apparent, the most obvious for me was input lag found in opsu. However, I didn't notice it until I tried osu.
After a few months of using a mouse I ended up purchasing a tablet, specifically the HUION H420. The tablet is incredibly cheap and works amazingly. It took a few weeks to get up to speed with speed and accuracy compared to what I could do with a mouse, and I am now vastly better than I ever was. I had real difficulty learning how to hold and use the pen however, mainly because I write with my left hand and control the mouse with my right. My right hand has never written before and didn't understand how to use a pen. I deemed learning how to control the pen in my right hand easier than using the other with a pen due to my left hand knowing how to repeatedly press button with speed and accuracy over years of gaming.
I still suck at the game however, but it's mighty fun.
As a passing tip, put a little piece of velcro on both the side your monitor and the upper part of your pen, it's a great convenient place to store it when not in use.
