Oh no, you're not the only one of course. This can be especially problematic when you have too many games/VNs to choose from - you can become less interested in just sticking with one of them and finishing it. But hey, you should be able to overcome it, I think. If you really do want to finish those VNs, then force yourself.... yes, force yourself to read just one at a time. Don't allow yourself to read several at once. I try doing it this way myself. I simply will not allow myself to read Clannad just yet, even though I'd really like to see how good it is right now. There'a also Steins;gate,
