A few months ago I was very angry with the approach they (WotC) decided to take with their new 4E, when I was playing D&D long ago (AD&D 2E, minis weren't essential. Now, with the pure tactical advantages given by powers to slide and push your opponents, you need a battlemat (tiles) + minis or token or something to represent adequately what's going on to determine the outcome of a battle. At the beginning I didn't like this. I saw it as a marketing ploy to sell more of their accessories. The problem is that you are not sure you're going to get the minis you need to play their games when you buy a few boosters, as every line of minis have a small percentage of minis you actually want. Why WotC is not releasing a non-collectible line for 4E, no they want you to buy their DDM and you're stuck with tons of minis you won't need to prepare your game. I want to have access to buy minis I need and nothing else. Anyway, I understood that it was to give more options to players, to make the game more enjoyable, and that you could get around the problem by playing gridless. It's ok, but still they could have come for a line of minis that was devoted to the need of 4E as separate from the DDM game.
Another thing I did not like was that you couldn't start the game with all the iconic classes, now you have to wait years before playing the classes you really want. Why is their no nature mage in the PHB I is beyond me, no more familiars for your wizards, etc. Now, if you want to get around the problem you have to design new classes with 80 powers, design paragon paths, and epic destinies, etc. It's a real nightmare. In a year, maybe the classes you want will be released, if not wait another year or until a 3PP release the class you want. Sheesh! Oh, I forget, you can also pay for DDI, and maybe you will get your class or race in advance.
Plus, they recently made the official comment that every book is now core material. Now you will have to buy every books, every setting to get all the material you need to play with 4E. That means you have to buy setting X if you want to play class Y, or race Z. Sure WotC is a business, but when RPGs were less commercial, it was a little bit different. TSR didn't pay 7 digit numbers to design a new edition. It's clear that they are looking for way to get a return for their investments. It was a corporate decision to go that way. It could have been more economical, why do they need a big staff on payrolls since 2005 for 3 year and a half before releasing a new edition? Sure they need to get paid, but what I'm saying is that the project could have been done in less time. Anyway, now they want their money back and the only way to get it is to make everyone buy all their books. I don't think I have the budget to buy every books to play 4E. That's why I understand some people are complaining.
Now, I'm less bitter, and more optimistic than a few months ago. I'm going 4E. And I like most of the change they did with the new editions. But I think 4E could have been done more economically. They could have made the process a less complicated one, and save a digit out of the 7 digit numbers it took to create the new editions.
