RTP only games can be great, but...usually they attract a lot less people.
Yes, some people might be weird about the RTP thing, it's taken as a sign of "laziness". Not if the story and mechanics are good though, perhaps?
There are, after all, a lot of "just another RM game"s out there.
If you map it right, and you definitely can, RTP is acceptable. It shows the time and effort put in, and looks pretty beautiful. First impressions matter!
And, @Miss Nile, you are a great mapper, I think you can make something fabulous even with RTP!
So maybe get a good working demo up with RTP? See what the response is and, if it's truly good enough, start getting people interested in following it's development.
Surprisingly, some heavy RTP games have sold over 100,000 copies (per Steamspy). And I know they are heavy RTP as I own them and have played them. So it CAN be done.
Thanks for the insights and support, everyone. I still have some to think about but I think I'll go with this.
@bgillisp Wow, now that's a surprise. Would you mind sharing some of the names with me? I'd like to take a look at these games. ^^
Data Hacker Initiation and Chronicles of a Dark Lord (original, the MV remake of it did poorly).
However...I think the reason they sold that many copies is they have been out for years. So it's probably more a case of they slowly built up a fan base than anything.
