I encourage you to use rollers and save some money. The gamification of training is not for your benefit, it's for the financial benefit of the people running the games.
I'd strongly disagree with this, but I depends how disciplined you are. I'm extremely lacking in the discipline department, and zwift makes indoor riding a hell of a lot more fun that just rollers. And because it's more fun, I do it more often.
