Twilight 2000 2.2e vs. 4e Celebrity Deathmatch

[HaplessOperator]

I've been split on 2.2 and 4e for a new game, after discovering the hype around 2.2 and giving the books a look-through, but i'm leaning towards a heavily modified 4e (feel free to sway my mind; it's probably easily done).

For those with experience with both, and having seen several threads running on the topic, I'm keenly interested in knowing what specific or cohesive changes anyone reading would make to either the 4e timeline or mechanics to bring a greater degree of verisimilitude and feel of 2.2 into the 4e setting and mechanics.

I want to reply just because of the title!
Having said that, I've never even seen 2.2e, just 1e and 4e.
4e is good enough- it's pretty fast flowing, has plenty of room to tailor the game/scenarios how you want and is sufficiently vague to fill in the blanks however you, the GM, want.
The fact that there are so many loose ends in 4e creates work for the GM but also allows the GM to tailor the game however they see fit.

There're a few draw backs.
The character generation spends too much time on background/history/moral code/big dream. That's a lot of effort on a PC that has 3-6 hit points and will die sooner than later. There's a strong "move the fiction forward" and cinematic feel for the game which trumps the grittier details needed for survival/military rpg.
There are only four attributes and three skills that align with the attributes. In my two months of playing, I've learned that if I sell out Agility and Intel and invest in Recon and Survival getting A rating in all of them- I'll have a really great chance at passing 75% of the challenges that come my way. That's too lopsided in my opinion. Also, there's not a lot of reason to get distracted by Specialties since they're so narrow- just invest in the skills and you won't need the specialties in most cases.

Still, it's fun.
I recommend 4e!
