It's very convenient to use in my opinion! I like how it lets me play with friends from all over without having to worry about hosting or anything of this sort.
The only thing i dislike about dimensionx was when you first start using your keyboard shortcuts they aren't always accurate so if someone else started playing at the same time some things might not work correctly. But other than that everything worked great!! We used dimensions x primarily to have fun, but we also made an online version where people could connect their own characters together into clans which helped us make new friendships through gaming.
