Steam has an extremely generous returns policy (play the game for less than two hours, for less than two weeks, and you get a full refund no questions asked) so you can give the software a try and if you don't like it just return it :)
If you do like it then I strongly suggest getting mods for it, which you can find all over the place, and which drastically increase the amazing things you can do with the software.
Lastly, I'd advise joining a Discord server - like mine! - where people can help you out, give you advice, and where you can post your creations for others to enjoy.
Have fun! :)
