Just buy a $10 or whatever it is subscription to DDI and then you have absolutely everything that has been released easily. I think the greatest irony here is that essentials doesn't genuinely replace the old books and really is a bunch of new options if you're just playing 4E. Personally though, what I've seen doesn't look to bad as a starting point and a much lower investment. Honestly if you like essentials you'll like the rest of 4E from what I can tell.
Essentials does do a few things differently, but it doesn't try to do everything again and make all previous books irrelevant. I hate to say this, but from what I'm hearing in this thread and elsewhere, Essentials doesn't replace the core books OR function as a 4.5. It adds entirely to the game and much of the old material is still 100% valid, useful and if you actually want to use it, necessary. The ironic thing about all of this is that many are going to complain they need more than essentials to have all the options (like rituals it seems). This does give me quite a chuckle.
I do agree updated core books would be fantastic though.
I was under the assumption that 'Essentials' would be, more or less, a complete package -- i.e. updated 4E, only with less options. Now that it's evident it's just an expansion set with slightly simplified rules (no rituals, for example) it's got no value for me. As I said, I want the core classes and rules, only without having to print out (and write it all in the books) hundreds of pages. I don't care about DDI; I use online and digital tools only rarely, because I honestly prefer books to editors and PDFs. Even if I *did* subscribe, it wouldn't help me during game play, as none of us use laptops. Again, If WoTC wants me -- and other people like me -- as customers, they should reprint the core rule books.
As I posted above, 4E "veterans" probably see this in a different light, because for *them* it's all about adding new options. However, I don't see 'Essentials' as a good starting point; it offers "specialized" builds like the Slayer and Warpriest. What if I just want to play a "core" fighter or ranger as my first character, and I don't see a monthly 5-10 bucks for referencing the class and powers as a good investment. And, yes, if I'm going to shell out a hundred euros for a game, I want the whole shebang for my money; not some sort of partial and optional expansion that's marketed as the 4E Revised ("Here's all you gonna need for the whole 4E experience"). It's not the whole experience, at least for the people who want to try the core classes and rules.
There's also the price point to consider; as I gather, the first boxed sets and books only cover Heroic Tier, right? What about those Paragon feats? Rituals? Epic feats and destinies? At which point do these 'Essentials' cost more than the core books -- which *do* give me at least *some* sort of complete package? I don't need to try out 4E with 'Essentials'; I know I'd probably like it. And based on what I've seen, me and my group would totally prefer the "classic" classes over the 'Essentials' ones. I just want the core classes updated and reprinted. However, investing money in the "non-revised" core books is plain silly from my perspective.
