Are people gonna read the article also? There is some nice insight in that.
I love Mario Kart, Forza, and GT. That's why I have hardware to play all 3 series.
I've certainly had more fun with Forza games in the last 6-8 years than the other 2. Not that they don't offer good/great games. There have been a lot of very good Forza (Motorsport and Horizon) games during that time too.
I probably put 20 to 30 hours into Mario Kart 8. In comparison I've probably poured 100-200 hours into Forza games in the same time period.
