Loving many of the mods you guys have suggested, which was one of my
ULTERIOR MOTIVES for posting this topic (the other was a veiled plea for an invitation to a server that wasn't terrible---read between the lines, people!)
Regarding some of the mods that have been mentioned:
Optifine: Second only to GregTech in controversy, I keep hearing conflicting things about this. Lately, I've heard that recent changes to Forge have made Optifine obsolete, and that it might be doing more harm than good to have it installed. I use it mostly because I find Optifine's zoom function too hard to give up (especially with a Portal Gun). Anyone able to shed some light on the use/value of Optifine in this day and age?
Gravestones (I used to play on harcore, as I hate dying and losing my stuff, but after having gone through about 20 worlds, I decided on playing adventure mode hard with this mod, plus using keepInventory is too easy)
...
WAILA (helpful to know what blocks is from what mod, and easy switch on/off keybinding)
Gravestones is definitely making it into my pack, and thank you for discovering it for me! I think "losing items on death" is alright in vanilla, but in modded Minecraft, the value of items in your inventory skyrockets to the point that some kind of compromise on this is probably a good thing---losing
everything to a lava derp is a bit too steep a price to pay, methinks. I like that this is a more balanced way to correct this than a straight "respawn with all your items" tweak.
Regarding
WAILA, does it have the same problem as the NEI tooltip does with ThaumCraft flowers/trees and Twilight Forest vines? (Weird things happen when I hover over these with NEI's highlight tooltips active: Greatwood Leaves turn to Silverwood Leaves, flowers turn pink, and Twilight Forest vines disappear like I zapped them with laser vision.) If not, definite must-add for me; I never know what half the stuff in this game does, especially since I haven't played with vanilla textures in forever (honestly, how do you people distinguish all the different ores?! That speckled-green rock could be Uranium, Monazit, Emerald or Mossy Cobble... and both Silver and Apatite somehow look like Diamond to me; it's even worse than the old Nikolite fake-out.)
Correct me if I'm wrong, but the trees generate by BoP aren't actualy new trees and as such doesn't drop sapplings and will only ever generate in new chunks. Then there are just alot of biomes it adds that I think are plain uggly/silly like trees made out of ice or the giant flowers that just look like big uggly blobs of color. But these are my opinions, and not fact. I think biomes XL has its own problems, like the pine trees being way way way to big, but at least they look nice.
Biomes o' Plenty: I agree that some of the biomes are a bit ... odd. I definitely reacted to the ice-trees with "dafuq were they thinking?", though I thought the native snowmen were cool. And yeah, agree about the flowers in the Garden biome---they could perhaps use a bit more detail, as they're blobs right now. I also don't like the sudden transitions of sky color between biomes (though I do love the various sky colors themselves). I doubt there's much they can do about this, but it would be nice if the change could be more gradual.
That said, I still prefer Biomes o' Plenty: It adds a ton of great content, and many of the biomes are simply better and more fully fleshed-out than those in ExtraBiomesXL, I find. I really like how each biome has its own little quirks (thorns, spring water, poison/poison ivy, etc). Crags, Jade Cliffs and Deadlands are especially awesome---I lived in a Deadlands biome during my 1.52 beta playthrough ("what the...
SILVERFISH?!"), where I made my base like an abandoned missile silo and pretended I'd survived the apocalypse
Millenaire: I've been eyeing this mod for some time, but I'm hesitant only because it's a big mod where a lot could go wrong and I'm wondering why it hasn't made it into any of the FTB packs. In your experience, are there config/stability/compatibility issues with it, or does it work smoothly alongside the other worldgen mods in the pack (including Ars Magica, in case anyone has run both together)?
Speaking of...
Ars Magica: If you like ThaumCraft, but you haven't tried Ars Magica, you're really missing out! I only discovered it recently, but wow this mod is incredible (and well-balanced, too, I think). Leaving aside the awesome multiblocks (Dark Nexus? Coolest. Thing. Ever.), magical devices, and (of course) the spells, there's also an awesome amount of worldgen that makes the Overworld a lot of fun to explore. It also works well with ThaumCraft and Magic Bees, with more cross-functionality in the works. I definitely recommend checking out Direwolf20's mod spotlights on it if you're on the fence!
