How about Return to Monkey Island?

How about Return to Monkey Island?

(Death's Door is awesome though)

I agree. *G*

Return to Monkey Island currently has 1518 votes.

Hiding the DLCs and extras you can see on the German version of the bestelling (all time) list the following:

No. 76 - The Secret of Monkey Island: Special Edition
105 - Monkey Island 2 Special Edition: LeChuck’s Revenge
110 - The Curse of Monkey Island
228 - Tales of Monkey Island: Complete Season
301 - Escape from Monkey Island

According to the support page GOG has 4140 games in total, see
https://support.gog.com/hc/en-us/categories/201400969-Game-Technical-Issues?product=gog

The Monkey Island series is doing well on GOG. There is no reason for Terrible Toybox, Devolver Digital and Lucasfilm Games/Disney to skip the game on GOG.

Is there a hidden byob? Some deals/games have a higher discount for me.

<span class="bold">Some good discounts. Too bad I already own all that I would've wanted :(.</span> Yes there is. ciem mentions it in the first post. For me it's 8% additional discount. So the 80% discounts jump to 88% as I already own a ton of these games.

I could get Shadow Warrior 2 at a 98% discount. Probably the highest I've ever seen.

Yes, there is. It's mentioned also on the sale page, but it's so messy it's easy to miss the info.
Titan Soul has quite impressive -98% discount :) ($0.34)

What do you mean, easy to miss? :)

EDIT:
Also, if anyone is getting Serious Sam 1st or 2nd Encounter, know that there's an ancient bug in the games where some weapons start shooting slower after a certain time period. A fix has recently been found and the 20+ year old bug is finally fixable. More info here:
https://www.gog.com/forum/serious_sam_series/fix_for_lasergun_slowdown_bug/post11

Some of the discounts are really great. I like the sale :)

And it's nice that BYOB offers are back (previous Warner Bundle ends today at midnight). The only problem is that the sale is really painful to browse/use in a new page layout. For those who do not own 10+ games I recommend adding everything you're interested to a cart and start removing to see how many games do you need to buy for a particular discount level (the discounts are properly displayed when a game is in cart). Thanks, now I see xD

PS. please not also that:
a) the sale's page informs "up to 90%", which means those -98% discounts are GOG's mistake :)
b) also some other Devolver games (not listed in the sale page) seem to work with the sale – e.g. Broforce, which has flash offer, may get even more discount...

Isn't there somewhere the old-school version as in the case of the Warner Bundle?

Good question – I've asked myself the same :D
Unfortunately I'm afraid the answer is: no. Or at least I cannot find it.

After noting that you could get to last week's WB bundle sale page by just adding "_byob" to the end of the url, I tried it for the current Devolver sale, and got a page with the old sale layout. This seems to work as advertised, and makes it much easier to see how much of the bundle you have/need.

Damn, I missed the bold BYOB. XD No idea how I missed that. :D

Woooow! God bless you, good man!!
Only now, compared to this, you can see how terrible the new layout is.
