If it's a campaign reskin, I wouldn't buy it. Co-op was so terrible on there it was nearly unplayable. If it is the campaign remade specifically under a new engine, I wouldn't buy it. Nostalgia =/= new game If it has the old multiplayer reskinned, I wouldn't buy it. All the glitches I have heard of would make me never play it. If it is a remade multiplayer under a new engine, I wouldn't buy it. Again - Nostalgia =/= new game So, I wouldn't buy it. There have been too many over glorified memories of what once was, because it was THE thing back in the day. Under all new graphics and mechanics the old and new would likely not be compatible. What you loved about the old game is a memory of what it was like then. There have been too many advancements and better things in games that would make anything from an old game seem antiquated and dull by today's standards. There are far fewer people who played Halo 2 online than there are that play all manner of other games online today, so I would expect the population to only be the true diehards trying to relive the past, but you can't get those moments back. The events that lead to those things you romanticize were then. The people you played with then that attributed to the 'OMG' events may no longer be around either.
