Well by that logic we should stop asking for better writing and for them to make a real RPG. Cause they sure as [censored] don't care about good writing or RPGs. Just looking at Fallout 3.
Interplay pulled off games with alot of skills, Fallout 2 has 19 I think and it works great. This was in 1997 and 1998. One would think with modern gaming which is supposedly far superior than games of Fallout's era, should easily pull it off.
Well, I said within reasonable limits, not "it's not worth it". I ask much myself too and expect to get none of it, but I do try to keep the perspective of who's doing the game. One can (and should) always ask for more and better, but asking for them to outdo themselves for about 100 fold (designing and balancing out 19+ skills with 3x the capacity of the previous ones, when the 13 was already too much) is going a bit overboard, don't you think.
Fallout 2 has useless skills too (there's no real, practical need for gambling, or two separate healing skills, for example), on top of which many of the skills were way underused. Not to mention the skills worked pretty differently there (meaning the skills that worked, actually worked).
I'd personally go for about 15 or so skills and design and balance them out as well as possible, and as distinct from each other as possible (along with SPECIAL itself). That's +2 for their previous lineup, and the cynic in me thinks they won't bother with it properly either even if they did add the extra skills.
