On another subject, the weekend sale is almost over. Why does Drod rate 5 stars? Is it actually that good and if so, how come I haven't heard much about it?
The original DROD (Deadly Rooms of Death) was released in 1997 and is one of THE most ball-breakingly hard turn-based puzzlegrid games out there. A somewhat revised edition was released along with the sequel's release in 2005, and that is the version to go for. DROD gets the flow of difficulty + new puzzle elements + new monsters just right, and with 25 HUGE levels you're not gonna complete it overnight.
DROD 2: Journey to Rooted Hold is a worthy sequel and is only slightly less fun than the original. Just as long, though. Every game since then has only had a small part of the development time of the other two, which means that their "new" features are somewhat cheesy and gimmicky and only drag the games down. I don't really recommend DROD 3 or DROD 0 (Gunthro and the Epic Bliunder) for this exact reason.
Let me give you an example: In the original game there is a game element called Tar. It's this blue gooey stuff that blocks your path unless it's chopped away, BUT you can only attack it from the corners of the goo puddles, not the sides. Which means that if you find yourself in a situation where you can't get at the corners, you can't do anything to it. Tar puzzles are some of the most hair-pulling puzzles in DROD because Tar may contain Tar Mothers which expand the tar every 30 moves, so careful timing is required in some places. In DROD 2 they added Mud, which is this red gooey stuff that blocks your path unless it's chopped away, BUT you can only attack it at the sides of the goo puddles and not the corners. As before, Mud Mothers may be present and the same 30 move expansion thing is still in effect. It's basically the same puzzle element with a slight twist. Then in DROD 3 they added Gel, which is this green gooey stuff that blocks your path unless it's chopped away, but this time you can only chop at it from inverted corners.
DROD 4: The Second Sky is due to be released in the next few weeks and it will introduce some new elements as well as conclude the main DROD story. It wouldn't surprise me if it contained a new "goo" type that just can't be chopped away at all. From the release trailer I can also see some new gimmicks that don't really excite me at all... quite the opposite, in fact.
As for Tendry's Tale, it's an RPG version of DROD... in a way. From what I can tell there are no random rolls involved, so
an aspie a clever player can probably get a perfect run through it by figuring out the proper sequence to do things.
