AC2:AC2 was 10x better than the original. Better mechanics, less repetetive and more story driven and a much better character to play with (Altair had 0 personality where as Ezio is great). If you couldn't handle the 6 tombs, even on higher difficulties, then you just fail. They were relatively easy, even if they did get progressively harder, but were very enjoyable. I honestly had no difficulty in completing them, and you're the first person I've ever heard complain of such a difficulty.
Urgency of fighting in the first? They've still got that daft counter attack system in the second as they do in the first. Fights are a simple matter in both cases. The fun of the game isn't wholey in the combat, that's always been repetitive because of the counter attack system, the fun is in the chase and in the exploration.
If you consider the second to be stale and the first to be...interesting. Then I am honestly simply bemused. The second had far more variation compared to the first. Far less of those stupid repetitive missions that you had to carry out in every assassination.
I'm also confused as Saint about the camera change comment. Honestly I found the camera perfect and never had trouble with it. I think I had more issues in the first.
The Witcher:I can agree with you that the first is a bit bugged, and to be honest, far to drawn out. However, having played the second one, I can say it's absolutely worth playing the first simply to understand the context of the second. If you take The Witcher, strip it down to it's bare minimum and rebuild it from scratch with a new graphics engine, combat system, improved story line, voice acting, quest progression ect. Well that's what the Witcher 2 is. However, it is also far more story driven than the first. The first you felt like you were endlessly doing random quests for no apparent reason. The second actually feels like everything ties in together, even if you don't have to complete every quest in order to finish the game. The second, simple put, is one of the greatest games of the year. I can easily see it being one of the best of the decade and considering it's only 2011...that's a big claim. Hell it has 2 entirely different chapters depending on which road you take. There are something like 16 different endings. And EVERY choice you make leads to a completely different game. It's re-playability scope is enormous with about 30 hours if you play every quest, but with each quest leading to dramatically different games depending on how you play them. The only reason I haven't replayed it again is because I have exams right now. So as I said, seeing as you can pick The Witcher up incredibly cheaply atm, it's worth the buy simply to lead into the second.
Half Life 2:I'm not even going to build an argument for that one. The game and fan base speaks for itself. One of the best games around, even now.
Fallout 3:When this first came out it was an amazing game. Beautifully crafted (if not a little buggy for some) and it had immense re playability. Looking at it now, it has quickly become dated, but honestly, I don't think you can get bored of it that fast.
Your comment on Mass Effect 2 and Dragon Age Origins being the same is a little confusing. I think you mean Dragon Age 2
The second was largely based on a similar style to Mass Effect 2, the first wasn't and was a complete game in itself. The second Dragon Age was disappointing due to a whole host of reasons that could take a while to detail. But I look forward to them pulling it back with a 3rd. Origins is an amazing game.
One thing I do commend Zisa on however is the recognition of some smaller, unknown games there. Divinity 2 (played through twice, both Ego Draconis and Flames of Vengeance) and in all honesty it's a fantastic game. It's one of those game that has lots of small touches all over the place that either make you chuckle or stare in wonder. The developers thought very deeply about it. It can be buggy, and the ending to the Ego sucks, but Flames makes up for it.
Another +1 goes to you for recognising Vampire. Loved that game, even if, like you say, you do need to download stuff to actually make it work, and even then it can be temperamental. But I loved this game from the start.
