Another way you could do the OP, is to talk what you generally like about the Mario series, some of your favorite games, what elements they have in common, what games you think are not that good(excluding spin-offs like those Mario educational games) and so on. Of course there are other ways of making good OPs, these are some suggestions, not rules, but again if you have something to say about Mario, then I am sure you can write more than one sentence.
Another thing to keep in mind, is that in the beginning you will have to spend some extra effort nurturing the thread, as in try to give replies to the first few posters in your thread with the same ID as your OP(so don't immediately change your IP). This will show that you are willing to have a discussion with anons, and after 10-20 posts the thread will have a life of it's own, and it's ok to switch your IP if you really don't like the ID system. In the past I have mocked some OPs that were just "What do you think of X game?" with no other replies from OP in the thread, and besides calling it a ">(1) and done", I might also ask OP "What do (You) think of X?", either to show people that OP is not willing to engage in the discussion, or maybe even give Op the chance to actually participate in the discussion.
I think this is more of a mentality thing, the OP isn't meant to just be a lobby you opened, and people will just participate due to induced demand, but more of a conversation that you are interested in starting, and willing to engage with.
I know I wrote a lot, and might seem like making a good OP is hard science, so I will reduce it to "Talk passionately about what you like, and engage with other anons about your passion".
