I've reorganised the Software and Games page of my library: Software.
The 17 applications listed on that page are my favourite tools. I use Ubuntu both at home and at work these days so there is less context switching to do and I can continue to use the same tool for each job.
The number of games is a bit of a worry – 96! It seems that I fell into Steam's trap of buying more games than I have time to play.
Right now I am playing a 4X (eXplore, eXpand, eXploit and eXterminate) strategy game called Star Ruler 2.
It is very good and a highly innovative example of the genre. I particularly like the way it models the relationships between different planets in your empire.
As a real-time game it makes me worry that I am missing something – turn-based strategy is more relaxing.
