Why don't I have a custom title by now!?
Get a meditation, calm down your nerves, forget about your Doom, forget about your experience, forget about your slaughterous desires, ascend your mind above that all, forget it all - and now go and play KDiTD on a HNTR difficulty (ideally from pistol starts).
I've tried it. And actually found the game enjoyable even then. Pistol suddenly felt fun to use, as my opposition was so low - in both enemy count and in health, as there are mostly zombiemen and imps. Shotgun much improved the pacing, and running through the maps in shooting joy was very satisfying. Chaingun and the rocket launcher became like hyper-powerups, lasting to the end of a level (as I've pistol started). Of course the game lacked the proper Doom challenge we know and expect. But it didn't lack a challenge completely. It was just... pretty much impossible to die. But I could at least give myself minor self-imposed challenges, like: "Let's see how much damage I'll take in this room, which gives me problems on UV." All in all, wandering the maps was enjoyable and the game had a spirit.
I thought it'd be cool to create a mapset and balance it out specially for this HNTR-like gameplay. For those who'd like this experience and don't mind a lack of challenge, or who really suck (I suck, but fortunately not that much). And the other people would play this mapset on Nightmare!, which would be beneficial for them too, definitely. Even non-pros could manage it and improve their skill while getting accustomized to fast + respawn gimmick. But, this toned-down (or just differently approached) difficulty must be present on UV of this mapset. Firstly, to make people to actually play the intended way (everybody play on UV or at least HMP). Secondly, because Nightmare! is based off UV.
Basically, the maps would stick to low-tier enemies with low HP and have interesting fun-to-explore layouts. But I'm not entirely saying to dumb down gameplay! Challenge could be present anyways, for example with traps involving monsters behind you, attacking from different angles and heights, in combination with environmental hazards... You know, the same things classic modders use to spice up their Doom maps. But "with a lower-scale budget" (regarding enemies and weapons), that's the idea.
"Doom, low-tier only."
Anybody agree with me?
