@aspvenom,
(Sorry about that. What I've tried to do is challenge myself not only by changing a letter, but also by mixing the remaining letters around. From now on whenever I see that you're participating in this game and there's a trend to only change one letter, I shall respect the trend so you can see how long the trend can be continued, as I've done below ...)

(Don't know if that made any sense.
