This deserves a thumbs up just for the chess implementation itsself which I think would be nice as a standalone mod as well (particularly the multi player variant could be nice for servers). The bot is extremely weak but that is to be expected. And the unexpected events actually kind of make up for it because no matter how good you are at regular chess calculating doesn't really help a lot usually bc eventually something like "remove all pawns" happens and everything is different anyways.
MineClone2 is also maintained, they're just not doing releases as often - I would recommend downloading the latest master branch at https://git.minetest.land/MineClone2/MineClone2 which is probably better than the current version on contentDB.
Also I suppose our dev team (mostly ryvnf and me) has been a bit more active recently.
The fact that it's lighter comes mostly from the fact that mineclonia does not have menu- and ingame music and has better optimized textures (i think).
That it appears more stable is probably mostly because we're generally quick at fixing issues as they come up - mcl2 has a few critical issues at the moment with fixes available but they have not yet merged them last I checked.
Yeah these compatibility things are generally known.
About the default thing - that's in 99% of the cases because a mod uses the node sound(functions) from default, i've been thinking about the feasibility of providing a compat layer for this kind of stuff for a while (might just be as an external mod though since other games could profit from it as well).
Regarding the xpanes, if you provide the exact error you're getting (or what mod you were trying to use that requires xpanes) that might be easily fixable.
Mesecons (heavily modified and used as redstone, but still named mesecons in mcl*) is an even bigger issue since that is going to be more or less completely incompatible.
These issues arise from the fact that parts of the codebase are very old (predating contentdb even i think) and a lot of times were just quickly added, modified a bit to be more like mc and then never touched again and hence this all applies to mcl2 as well.
In general i can say your criticism is completely justified and something i've been thinking about how to best fix before, it's just not an easy decision to make: renaming the mods probably needs to happen sooner or later however.
Thanks but to be fair there are not too many differences to mcl2 at this point. It's mostly that mineclonia does not have the tons of music files mcl2 has recently added which almost doubled the size of the game.
For some context: the check is there to prevent hackers from accessing the enderchest inventory without and actual echest. Regarding detached inventories I recommend taking a look at mcl_entity_invs that basically manages "ad-hoc" inventories for entities like chest minecarts and saves the content in a table in the entity.
there are many clones which are similarly close to the original - the most well known ones probably being openttd (transport tycoon) and freeciv (civilzation). But you might notice that list even has a number of minecraft clones - and yeah some of them are similarly "clones" - or "reimplementations" or whatever anyone likes to call it.
The fact of the matter is if microsofts sends a dmca takedown it doesn't seem likely anyone would go to court over it. In light of that there is basically 2 things we can do: change everything that migh piss of microsoft in the slightest and live in constant fear or just accept that this risk exists.
You might not realize this but the codebase of mcl2 is huge. Going that first route would be considerable effort. And its not like we can't still do that if something like it were to happen.
But foss game clones aside, as long as the appstores are full of minecraft clones that ... yk cost money or have ads its probably realistic to not worry too much.
Not giving you an upvote until legal problems get resolved.
Essentially meaning until the project doesn't exist anymore - the potential copyright problems are a fundamental thing, aren't they it's not like that can be "resolved" by changing a couple of names here and there.
Furthermore right now there aren't any legal problems (i am aware of). It's not like we're talking about criminal law. It only becomes a legal problem at the point where the holder of the alleged copyrights decides to do something about it. There is really no clear right and wrong with this stuff (or anything in civil law tbh)
Now i'm not saying you're wrong, indeed i've made similar points before, but it's not like you're definitely right either. Many clones of games exist and there are court rulings to both sides.
Pretending this is a clear cut issue is neither doing the issue itsself justice nor the people who have put hard work into this. And diffuse fearmongering ("the game is a legal hazard for Minetest community" - how ?) is probably not helpful either.
To make it very clear: you are not a judge assigned to a copyright case regarding mineclone2 (afaik?!) in turn you are not who decides what is a violation of copyrights - a maybe similar real world case:
