Alright, so after a little testing here and there, here's the mods I'm using so far:
Forge Mod Loader (Obviously)
Code Chicken Core (For NEI) -ChickenBones
Not Enough Items - ChickenBones
Dynamic Lights - AtomicStryker
Ruins Mod -AtomicStryker (Config'd to make ruins a lot more rare.)
Damage Indicators - rich1051414
Mine & Blade: Battlegear 2 -nerd-boy (This mod is still in development, so is very basic at the moment.)
Minefantasy - AnonymousProductions
Rei's Minimap -ReiFNSK
Ars Magica -Mithion
Backpack Mod -Eydamos
Biblocraft -Nuchaz
ExtrabiomesXL -MisterFiber
Invasion Mod -Lieu
Falling Meteors -AlexDGr8r
Timber! -TehKrush
Rotten Flesh to Leather -EpicBlargh
Two other mods I attempted to add were
Microblocks -Immibis
Weather & Tornados -Coros
Both of these mods did the annoying Black Screen crash, the kind that doesn't give me a crash report I can use to figure out the problem. So that'll have to be figured out to use those.
A lot of Coros' mods look great for this kind of world actually, however most of them are still in development and/or are outdated atm, but I'll keep an eye on him for now.
