Welcome to Subsim wawrzul.
Nice Introduction as well. If you are looking for sims, you might want to look into Cold Waters as a number of our members have posted favorable reviews. In addition, some of the older Silent Hunter Sims from SH3-5 that are heavily modded have excellent gameplay once the bugs are worked out.
It might interest you to know that there are other musicians in Subsim, both professional and amateur. As Eichhörnchen already said, we like other things here besides computer games like music and cars and many other things. We like to talk about them as well so there is something for everyone to like at Subsim.
If you have any favorite music, be sure to check out the Subsim Music thread and post your favorite music or performances there as well.
Welcome aboard and enjoy your time here.
