The video looks very good
I only have few comments related to the text, here are my corrections/recommendations:
A game to satisfy you desire
for bashing those trespassing
fools who dare oppose you!
It's time to show them
They better...
... STAY OUR OF YOUR
DUNGEON ...
Command your dungeon to
hoard your wealth and
power to overcome the
other factions of the Under
and Overground.
RULE ... THEM ... ALL!
This Game Project needs YOU!
It's a Free and Open Source
Game for everyone... and it's
in need of any industrious goblin
hand that want to aid it to become
the best RTS game ever made!
We are looking for artists,
coders, and testers. You can
already download alpha versions
on our website.
Come join the eternal battle between
6 powerful factions.
What are the planned features?
* Build dungeons with sinister traps
* Train creatures to do your bidding
* Explorer the depths of the underground
and the heights of the overground
* Annihilate you enemies or let them
kill each other and wipe out their
sad remnants
* Upgrade your abilities with the
skill tree
* Take the challenges to new heights
in multiplayer
* You will never loose too much thanks
to the ranking system
Edit: I just saw the other video and updated this post accordingly.
