For a birthday's present without BW expansion (it would cost too much without even knowing if he will like it), so here's my question:

Should we add some house rule to even out the game?

Like increase the cost of the Archons to 2 gas to prevent Aldarchons!

or increasing nuke damage to 3 unit destroyed?

any other idea?

NO.  It really doesn't need any house rules.  Especially if you haven't even played it yet.

I have read the forum and it kinda seemed that the vanilla needed some tweaks.. glad to hear it is ok :D

Can't find the edit button:

The Firebat is ok?

The firebat isn't the best unit in the world but it has a few uses.  Not really a balance issue worthy of house rules that would complicate your first play.

There isn't anything show stopping trust me.

Well, you will surely have troubles with understanding some rules, but you will find them during gameplay only.

You will find most of answers in the rulesbook. But remember to read FAQ before starting the game:

Thank you all, i've already read the rules + faq, and much of this forum, so i hope i will not have too much problems.

I'll make an AAR of the first play :D
