I'd prefer that rather than there being specifically one new resource every X levels, have certain resources that are gatherable at the same level.
On top of this, introduce some "fantasy" resources (such as stone trees) that require certain levels in mining AND woodcutting. Or other things to generally
broaden the amount of things there is, as it is rather bland and linear. Look at the amount of stuff there is to do in Runescape (as much as I hate to pull that example).
Commence
OH GOD, WOOOOORRDSFor instance:
Woodcutting
| Lv. | Resource |
| 1 | Pine |
| 5 | Oak, Willow |
| 15 | Maple, Mining 15: Graveltrees |
| 30 | Yew, Mining 15: Stonetrees |
| 50 | Moonwell Trees |
Mining
| Lv. | Resource |
| 1 | Copper, Tin |
| 10 | Silver, Gold |
| 15 | Coal, Iron, Woodcutting 15: Graveltrees, Woodcutting 25: Stonetrees |
| 30 | Mithril |
| 50 | Adamantite, Obsidian |
In this example, Graveltrees yielding a Gravelwood Log with a small chance to yeild an ore of a precious metal (silver or gold), and Stonetrees yielding Stonewood Logs and having a small chance to contain Iron or a smaller chance to contain Mithril - plus gravelwood and stonewood having their own uses (though what these are I can't really say). And just to mix things up a bit, perhaps Graveltrees and Stonetrees could require the first 75% of their health to be done with a pick and the other 25% to be done with an axe. Weakening the surface, as it were.
On top of interlacing skill trees to add a bit more depth, you should also look at the idea I mentioned for charcoal in crafting - when smelting ores, it should take X units of coal which can be substituted for X*2 units of
charcoal, which is made from different types of wood.
Consult this table: (yes I like tables)
| Wood | Charcoal |
| Pine | 1 |
| Willow | 2 |
| Oak | 3 |
| Maple | 3 |
| Yew | 4 |
And Moonwell Logs are not usable as charcoal due to their ~*mystical properties*~. But Clockturn, you say, Oak and Willow are the same level to be chopped but Oak makes more charcoal!
Well that's not a mistake. Oak is a very firm wood but Willow is much more supple (assuming this of course from the general shape of a willow tree). It's less dense, thus, less charcoal. Plus - different wood, different use. Make bows from treated willow because it's not so solid, or something.
The point of the whole charcoal/coal idea is to add a bit of 'alternative variety'. Having multiple ways to do the same thing is good - it makes people feel less locked in to the same thing over and over again. If I need to smelt a heap of Bronze but I can't mine Coal, but I
can chop Oak, that puts me in a good position - as one log of Oak is effectively one and a half units of Coal. (Of course, I would need to be able to make my own charcoal. At the very first crafting levels - I'd say charcoal would be unlocked at 5 - I'd have to buy fuel from NPCs.)
Oh and Pine is just stuffty. Ignore Pine. It requires 1 Woodcutting to encourage its prompt genocide.
Edit: Deliberately not showing farming no love. It can wait till another huge post this one is big enough
