Never go into designing games - I'd just end up making a game that I want, not a game the consumer wants. Given how I dislike quite a lot of games that do well, I'd be a dismal failure at game-designing.
I'd review games - it's fun to do, and you can be as subjective as hell and get away with it. It's basically your opinion. I don't really think it's an easy job (the sheer amount of games you'd be forced to play would be a chore, and I don't think it pays very well), but it doesn't require that much thought. Just play through it enough, write down some points along the way, expand upon them in the report, and viola, you're done. As long as you are prepared to play through a lot of games on a schedule, and as long as you're at least a functional writer, you can probably review games.
Creating a webcomic - I couldn't stand doing that. To get anywhere, you have to update somewhat regularly. You'd have to wade through email after email from fans. You'd have to maintain a regular blog. I couldn't handle that much. It requires to much "interaction" with the fan base.
Program Games? Hell no. Far, far, far too much work. To design a reasonably good game, you have to really know your stuff, work for hours upon hours, be incredibly dedicated, fiddle around with mathematics, attend meetings, and if you work for a company like EA, get paid next to nothing to boot. Designing a game might be hard, but programming one is a really, really bad job. A designer gets paid reasonably well. A programmer gets treated poorly and paid poorly, because he's replaceable.
