In ur opinion which games do you think are better/worse in the new generation of gaming then they were in the last one?

I can only say from a Nintendo point of view as i have a wii and ds now and had a gamecube and gba before. More opinions from other Nintendo owners  aswell as Xbox/360 and PS2/PS3 owners are welcome XD

Wii:                            Comparison:           Gamecube:                       Remarks:

Mario Galaxy                better                  Mario Sunshine                  The cleaning thing of sunshine wasnt my thing                                                                                                                              xD

Super Paper Mario       worse                  Paper Mario:TTYD               It was so much better on gamecube, i still                                                                                                                        could cry

Mario Kart Wii              better                  Mario Kart:DD                      The battle mod was better on gamecube but                                                                                                               with online and overall  it's better on wii

SSB Brawl                       ?                        SSB Melee                           No clue as i only have it for gamecube :>

DS:                            Comparison:            GBA:                                 Remarks:

Zelda PH                   worse                        Zelda Minish Cap             Ok it's a comparison in progress as i                                                                                                               haven't finsihed Hourglass yet but so far                                                                                                               it's worse in my opinion

Mario & Luigi: PiT          ?                            Mario & Luigi: SS               I'm playing Superstar Saga right now                                                                                                                and loving it, haven't started Partners                                                                                                                 i n time yet, so no idea 

Children of Mana          ?                            Sword of Mana                  Haven't started both yet so no opinion                                                                                                                    right now

I'll simply copy your layout :P

360:                            Comparison:        XBOX:                               Remarks:

Halo 3                          better                  Halo 2                                Slightly better single and multiplayer mode

Amped 3                      worse                  Amped 2                           Gameplay is too arcade-ish

Dead Or Alive 4          worse                 Dead Or Alive 3              Overall it should be better, but the difficulty is

                                                                                                                  way too high

To add to the OP's list, Superstar Saga is widely considered to be better than Partners in time, and just about anything is better than Children of Mana.

And I liked Super Paper Mario better than PM2...

Devil May Cry 4 worse Devil may cry 1 and 3
Gta Iv worse San Andreas
Soul Calibur Iv better Soul Calibur 3

I'm going to assume you know the platform(s) for the games. Oh and this is not a measure of their quality, more like how they fare compared to the last-gen game.

This Gen:            Comparison:            Last-Gen:                 Remarks:

Halo 3                   Better                     Halo 2                   More cohesive single player and Multiplayer additions made it better

Devil May Cry 4     Worse                    Devil May Cry 3       Lower difficulty, not the jump up in quality that DMC3 was from 2.

Forza 2                       Better                  Forza                      Improved graphics, more cars, slightly tighter controls.

Super Mario Galaxy     Better              Sunshine                It was like Super Mario 3 compared to Super Mario 2. Enough Said.

 LoZ: Twilight Princess   Worse            LoZ: Wind Waker      Lack of innovation and the same game we've played for a

                                                                                             decade. Yes it was the spiritual successor to OoT, but that was a 10 year old game!

R&C: Future Tools        Better            R&C: Deadlocked         Easy Win. Would have lost against Up Your Arsenal though.

Mario Kart Wii       Worse                 Mario kart DS           To make it interesting I used DS rather than DD which sucked. Loss of any skill involved in drifting/powersliding hurt this game big time

PS3:

GTA 4 - WORSE than GTA SA

MGS4 - BETTER than MGS3

DMC4 - WORSE than DMC 3

COD 4 - BETTER than COD 1

ES 4: Oblivion - BETTER than Morrowind
______

Wii:

SMG - BETTER (MUCH MUCH) than SMS

SSBB - BETTER than SSBM -- subspace emmissary FTW!

Zelda : TP - WORSE -- windwaker

MK Wii - WOSRE than MK DD

oh yeh i forgot about Zelda Twighlight Princess and i enjoyed Windwaker also a lot more
