Just a theory, but it seems like your review score drops significantly if you use the same engine on the same Topic/Genre combos more than once, period. The the drop decreases as more time passes, but if you get a perfect score with one Topic/Genre, you will never get a perfect score with that combo again using the same engine. There also seems to be a smaller decrease if you use the same engine with games of either the same topic or genre multiple times. So if you get a good score with an RPG on one engine, making another RPG with the same engine will result in a slightly lower score. Ultimately, if you want to focus on specific genres/Topics, you're going to have to build a lot of new engines to get lots of new sales.
