RE Bundle at $35 is great, only provided you don't own most of this already - which probably will be a problem for most PC gamers here.
$10 is really good, provided you're missing RE4: UHD (this QLoc Version on Steam), RE5 Gold, and RE6 altogether.
$20 is pretty good, provided you're missing RE2 Remake, RE3 Remake, and RE7 altogether. Even better, if you're missing stuff in earlier tiers, of course.
$35 is good, provided you're missing RE2 R, RE3 R, RE7, and RE Village [base] altogether. Of course, even better if you're missing previous tiers too.
Worth noting - RE7 DLC's might not be super-long, but they're worthwhile and important for some story-stuff. Namely, End of Zoe here is important; see my Review on it, as it should take 2-3 hours. Get End of Zoe or Season Pass, whenever it gets cheap.

More RE7 stuff - make sure to add Not A Hero DLC to your account, since it's free; it's 2 and 1/2 hours or so. Definitely worth playing, to play as Chris, as he basically cleans up the mess from everything that went out in the base-game.

About RE6 - never owned any of the DLC's. Not like you probably need it. Most of the DLC's are MP-stuff and/or other game modes. Base-game and its 4 campaigns are so bloated anyways, you probably won't want or need any of it - should take most gamers double the amount of time of a typical RE game (i.e. 10-20 hours for a normal RE; meanwhile RE6 one can take 30-40 hours). RE6 has a whopping 4 campaigns. I like namely the 1st campaign (Leon's) and the last (Ada's). Ada's should be done last...b/c it fills blanks and plot-holes up for the other 3. As for the two middle campaigns, they overlap w/ each other too much, poorly placed, and feel have too many of the same boss fights, mini-boss fights, and repetitiveness of the same areas (tons of overlap in the two middle campaigns w/ each other, which hurt it). RE6 is good, despite its repetitive-ness and being so flawed, holds it back from greatness. Not being able to skip certain Chapters, scenes, sections you've done before in other campaigns when you're not in a different position really does NOT help.
RE Revelations 1 and 2 are BOTH underrated as can be - and are better than RE6, IMHO.
RE4 UHD, RE7 Gold, RE2 Remake are probably the best RE games here. RE2 Remake is the best game here IMHO (What a masterpiece), even though RE4 UHD Steam-version (aka listed as RE4 2005, even though it's really RE4 2005: Q-Loc's 2014 Remaster) is my favorite.
RE4 UHD is way better (with mouselook support, super-important here) than the OG RE4 Retail box edition from UbiSoft (which lacks real mouselook support and you aim w/ the damn keyboard controls - WTF?). Make sure if you get RE4 UHD here, you grab RE4Tweaks and turn on Subtitle-support for cut-scenes. Get that here...

RE5 Gold is pretty good. Base-game's a blast, even though it's way more action-y than RE4. Great port technically, though - especially when it came out; major improvement on that part over RE4 OG Retail Box version. Though, I prefer RE4 (any version) as an actual game. RE5 DLC's are good - and I'm glad that's included here; makes life easy here. One of the DLC's rule b/c you go back to the old mansion in RE1 and revisit are certain important character...and there's an awesome boss fight there too.

RE Village is awesome. It many ways, it feels like a 1st person RE4 gameplay-wise and combat-wise; and design-wise, too. Though, it feels like a combination of other RE stuff too. Definitely worth playing. I ain't bought/played Winters expansion yet.
