1. have tech dungeons, large tech dungeons & magnetite ore spawn twice as much in Menelaus and twice as much again in Tyros - would give more of a reason to go back there and spend time there.

2. players loved the new open underground in Menelaus, but maybe replace all vanilla stone in the dimension with the Menelaus stone or some other variant of it - would immediately give it a more exotic alien feel, and people have more than enough stone in the overworld.

3. love the lived-in jungle look on Tyros, but maybe replace the vanilla jungle trees with smaller variants of the glowmelo trees or maybe just re-colour the jungle trees to something more like the pink/purple colour of the glowmelo trees - would give it a more alien atmosphere.

4. replace grass & stone in Tyros with new Tyros versions - makes it more alien, less overworld.

5. stop the spawning of any passive mobs that aren't part of your mod on Menelaus & Tyros - seeing chickens and pigs or animalia animals immediately makes the place seem less Alien.

These are good suggestions and I am sorry I did not respond in any way :S

I add my own suggestions I had already made since a long time in the list

• Liquid Bioterium, Glowtite, Retium, Quantanium, Wakurium liquid since liquid Neon exist. It could add more gameplay and recipe possibilities
• Compatibily with Tinkers Construct, with maybe TConstrust tools, especially if liquid metals are added.
• Possibility to modify vein size, max and min height for ores.
• Wakurium and Quantium crystal block and sand should generate in Tyros for making this planet more interesting and unique.
• Neon should be renamed into Neonium or something similar for not confusing with Neon gaz. Glowtite could be renamed into Glownium for fitting the other metal names.
• Menelaus could be Mars, and Tyros could be Venus, which has been terraformed a long time ago by an advanced alien species, with strange technologies and magics, the same which left tech dungeons on Earth, Menelaus, and Tyros. It would enable to build a consistant and logic lore to FuturePack, and gives more ideas for future additions on Menelaus and Tyros. I would explain too why Menelaus and Tyros looks a bit like Earth, which has been maybe terraformed too.
