It is worth getting both Witchers at this price? ;o

They have been 75% off many times before. So, yes, you should wait for the summer sale.

The price is good. Witcher 2 is much better than Witcher 1 I think

Witcher 2 probably gonna be 75% off. I'll wait for summer sales

Do it.

Current price is cheaper than previous 75% sales ;)
I just got them, for this price those few extra percentages are only a few cents ;)

yes

Yes, both games are great and worth full price :)

Should i get 1 first and wait for Summer Sale for 2? :3

At what price?

If you've been waiting for their sales and are going to play them right-away then get them both now, great prices for great games.

If they're going to your Steam backlog then wait. They might get cheaper or at least same as current prices during Summer Sale, no point in getting them now.
