I spent a while playing with worldgen to find a nice vanilla mix with volcanoes galore.
I just made this map, it parameters are fun without these exact seeds, but I generated about 10 tonight before finding this one that has a lot of volcanoes with 3+ biomes in a 4x4 embark near water like aquifer or river. Scarcity is 666 resulting in lots of embarks with shallow metals + deep metals + flux.
It has boosted numbers of good and evil biomes and is pretty close to as many biomes as u can fit on a large region map. I remember from tweaking these back in about 40.9 that I had to adjust some of the variance numbers down or fail to create from too many biomes.
I will play this map a while and hopefully abandon many a fortress to ruin before attempting some of the harder embarks
like: joyous tundra + terrifying frozen sea + volcano
or simply terrifying aquifer glacier volcano. (both with multiple biome + metals & flux in 4x4 embark of volc.)
I counted at least 6 starts with my resource reqs of 2-3 biomes shallow, deep and flux + volcano and surface water (partial aquifer or river) in a 4x4.
It is very very spikey mountainous because of my parameters.
Lots of 12+ cliff faces on these volcanoes.
I boosted numbers of megas and kept the time short (112 years) to have less of them killed off.
Oh and some of the parameters lead to extra forest wetness, minimized frozen waste(though still plenty of starts) and minimized speckled oceans, lots of mountains in smaller ranges.
I hope to enjoy it, and hope someone else may
