I'm actually playing New Vegas right now and like it better than 3 (other than it is prone to more glitches & freezes). Like everyone else mentioned, the gameplay is exactly the same so don't expect anything mind-blowing.
It's definitely worth it if you are a huge fan of 3.
1. Search Bar for Games.
Right now we have to browse the games alphabetically if we want to follow a specific one. It would just make it more convenient to search the title of the game you are looking for instead of going through the alphabetical list of titles.
2. Threaded Reply Order
The replies to answers are threaded, but it seems backwards to me. The first reply is shown last. I feel that it should go in the same order as the people replied. 1st reply, displayed first, 2nd reply displayed second, etc.
You have to tap the select button to bring up the Nanosuit upgrade menu. Holding select down gets you to the weapon upgrades.
The nanosuit upgrade menu is actually sort of confusing as each finger represents a different upgrade. To scroll through the various upgrades on each finger, keep pressing that fingers button. When you're on the upgrade you want, I believe it's R1 that lets you purchase the upgrade.
Short answer: Meh.
Long answer: Not a big fan of this. From what it sounds like the paid portion is going to be rankings, tournaments, clans (probably more in-depth than just a clan tag), choosing opponents, and stuff of that nature; although that's all speculation. The paid portion will mostly be based around the website they are building.
Like Teppoudo already said, the online multiplayer will probably still be free, at least for now. That is part of the reason I'm not sure if I want Elite to succeed. If a ton of people are willing to pay for this, year after year, less things will be free. Companies can take advantage of the fact that people are willing to pay each year (Good examples are Madden which never changes, and even CoD which only has minor changes each year).
Eventually I can see it leading to having to pay to play online matches, which is less than ideal.
It's hard to compare those games since they are in different genres. Overall I think Uncharted 2 is the best game. That being said, the other 3 games will probably give you more hours of gameplay because of their multiplayer.
Unless you're getting a good deal on Black Ops, I'd wait until November for MW3.
The first Tomb Raider is simply called "Tomb Raider" and was for Sega Saturn and the original Playstation (I think they re-released it for PS2). TR2 and TR3 I believe were directly sequels. Here's a link to info about the other seven Tomb Raider titles.
The first Tomb Raider was incredible for its time, although you won't be blown away by it today. The first 3 were great, but I haven't played the more recent ones.
