One of the requests of Gamism is fairness and balance between classes. While 3e failed at this goal I think it made an attempt. Since 4e fairly succeeded at balance it would probably be the most Gamist version of D&D. Might be hard to claim that 1e and 2e were more G than N & S.
I agree.
OD&D/Basic D&D were just that - Basic, and therefore provided equal support for all styles as it didn't specifically support any style.
I think the mechanics and rules of AD&D (both editions) were more complex and a bit more gamist, but the mechanics were meant to support certain styles of characters, not certain styles of play. I think they still equally supported all play styles.
3E was even more complex mechanically, and tried to support absolutely any style of character, but became a much more simulationist type game. I don't think 3E made a significant attempt at class balance, but this was addressed with 3.5E.
The revisions in 3.5E added some fairly strong gamist elements to the 3E mechanics, but ended up fighting itself because of this.
4E is definitely the most gamist oriented edition of D&D bar none, and I believe at the sacrifice of simulationist elements. However, I believe narrativist play is still just as equally supported under 4E as in any other edition.
I hope 5E can equally support all play styles, but we shal see. I hope for just the reason that 5E may not completely succeed at this, that at the least they maintain the 4E portion of DDI intact (I would also like to see the same added for all editions of D&D to DDI, but that's probably unlikely).
But, I am very hopeful that 5E can pull it off. So far, it sounds really good. And the underlying philosophy sounds almost perfect. However, before the release of 4E, I thought the underlying philosophies being expressed about it sounded perfect also...until I had it in may hands and actually read the finished product.
So, we shall see...
