So, like, what's the thing of these maps? On the screenshots, they don't look too out-there and the majority re-use in-game textures and assets, so...do they have any special gimmick? Or, are they particularly fun? Sorry if I'm coming as rude, I'm just curious.
I won't lie-- this post had me floored for a bit. For the past five hours, actually. This wasn't a question I've ever seen anyone ask in all my years of being a part of this community, and one neither I nor anyone I hang out with knew how to answer. It took a while for me to piece together that newer players such as (seemingly) yourself don't have the years-old context of packs like this being released, instead having only the context of main expansions and sub expansions such as DOS Reborn or Rock Force to base your expectations of what side content gets released on. Sorry if that assumption's incorrect!
So to answer your question proper, there isn't really any
thing to this pack. It's not based on any particular game, the maps don't follow any central gimmick, nothing like that. Like custom tracks for SRB2 Kart or maps made in Halo's Forge mode, the purpose of this pack is simply to add new content. You may have seen packs like Legopack, Rozpack or Sharp that do roughly the same thing.
I realize that when put in writing, that's not as exciting as a new, fully custom set of maps like what DOS came out swinging with. However, packs like this are a chance for individual creators to push their own style in a set of maps truly unrelated to one another and to any other content. That can be a chance to show off your architectural and texturing skills, to experiment with new styles, or simply to get ideas out of your head. The (roughly) yearly mapping jams are another outlet for this, and a popular one at that-- Paper Jam was the highest turnout jam ever got!
Your second question (Are they particularly fun?) is a little bit more brutal, and one that I can't answer for my own maps without looking super biased. I
do know that Llama's side of the pack is a ton of fun, though, and I
am proud of my own set. Rest assured that I wouldn't intentionally try to release something that wasn't fun*! At the moment of typing this post, there're 3 servers running the pack (Classes, Roboenza, and Scorched Earth/Havoc), so if you don't want to just take my word for it, go and check it out!
*Mirror Mode is an exception to this and I'm not sorry for that monstrosity
sorry if this came off as condescending or hostile or anything I just had a really hard time understanding what the question really meant
