And which areas may be those that you felt lacking in the original, apart from the content?
Loads. To be honest, the patch that came with Finland almost broke the game for me. I continued to enjoy it until Dirt 4 came out, but unfortunately that destroyed my interest in both. DiRT 4 fixed the immersion-breaking weight issue from DR1, but the stages in DiRT 4 were so immersion-breaking themselves. Not to mention D4 completely breaking my favourite cars, the H2 RWDs (and, personal bugbear, moved the Stratos into a different class to the Escort and 131 for some unknown reason).
So, in summary:
- The weightlessness issue was the big one. Completely immersion breaking. It's one reason I'd love to see the DR1 Finnish stages back in DR2; I thought the artwork was superb, but the stages were completely broken with powerful cars.
- No rally multiplayer. D4 did this well but I wasn't playing it when they introduced the leagues system at last. Looking forward to finally playing in a couple of leagues from forums I'm in.
- The first game always felt very stripped back, as it was basically a tech demo. That said, I liked its basic approach to career; I could focus on driving. D4 tried to do too much but ended up feeling 'gamey' in its approach (ambitious done badly). DR2 looks like a reasonable middle ground.
- Lack of ongoing support and updates. I wanted the 'gravity' fixed and more content to be added, so it was more like Assetto Corsa and other games in that it evolves and improves over time.
- You said 'aside from content' but that ended up being one of the major ones. It's why I personally would rather have 3 'old' rallies, completely updated with the new features, than 1 'new' rally; I just want more kilometres in game. I've not touched DR1 for a couple of years really, so I don't remember the stages in detail.
- One last bugbear; I hated that career mode gave you worse weather on advanced difficulty levels. I guess DR2 will be the same but hope they'll change that if so!
The other new things are all logical steps of progression. Tyre options, surface degredation are both interesting new features. I fear (after D4) that they may not be able to tailor the AI to cope with it.
