Halloween sale, and is it worth it?

I don't think GTA complete pack has gone any lower than 80% off (on steam). You could get it off GMG and tack on another 20-23% off when they have it on sale. When that will be? I can't tell you.

GTA 5 - I believe this is the largest sale it has had so far. It was on "sale" for the summer sale I believe, but they only bundled it with those shark cards and left it at full price.

Day Z has had a bigger sale.

I think this might be as good as it gets for L4D salewise, or at least this has been the lowest so far, I'm not miss cleo and can't tell the future. But again, its on GMG for the same price, tack on another 20-23% when you use their vouchers.

If you are interested in L4D series, buy only L4D2 since L4D2 includes all the maps and characters L4D1 had. There are currently a lot of online players and servers and mods for L4D2 but almost none for L4D1. And 80% off is a fair discount. It's a reasonable decision to buy now.

GTA V is relatively a new big title so it barely gets discounted. You can wait till it gets 50% or 75% off like other titles but it'll take months or even years.

Is it me, or the Halloween sale banner is totally missing from main page or deals, or even news? Right now I cannot see such a sale advertised on Steam at all, and it's either someone's flop that it's not up until now, or GabeN minions got totally lazy with doing sales.
