I used to play Starcraft a lot, but i don't know anything about mods, extensions, multiplayer, etc.
From where can I download the best current release (official or not, i don't care) + maybe some extra such as better/HD textures? Is there any easy path to follow?
I cannot tell from your comment if you're aware of StarCraft: Remastered - it's $15, includes original/Brood Wars, and has modernized skin, but plays identically (and is compatible with) the original. $15 USD.
to be clear because this is often a point of confusion (I believe it was done intentionally to be confusing but I digress). The remastered client is actually free, the HD skin (and ladder play) is $15. So you can play online with custom maps and the campaign and so on for free.
