Backloggery is great, but it's not exactly visual. There's no game database, you add games by name yourself. At least it ensures that whatever you're trying to add can be added. Adding and removing games feels easy enough for me, but depending on your needs, you might disagree. There's also wishlist functionality, and you can specify games you've owned, borrowed, or rented in the past. There's also different states for game completion, i.e. unplayed, unfinished, beaten... You can also rate games and keep track of the number of achievements etc. you've collected for your games. It's pretty versatile, but keeping track of all the details requires manual labour as there's no integration with any services (e.g. Steam).
