1. The game scales very poorly out of the box to older hardware. Yet 2 mod teams can and have fixed it very very quickly and I read in like 40 lines of code?
2. The netcode is poor.
3. The sound coding is poor.
4. The rail gun is easier to hit with, I dont care if its due to hitbox, rail projectile hit box, movement speed, acceleration, whatever, it is. And ppl who say its because we have just gotten better are saddly deluding themselves.
5. Simple things like LG length, SG spread, and so on are off.
6. The default maps where horrendous before being tweaked by the community. Why? Because the devs believed that making it easier for ppl to get frags due to a critical lack of armour on the maps would increase fun. Instead it became instagib and negated any kind of depth that quake has had for years.
7. Autodownload and so on issues.
8. Finally that brings us to the most damaging issue. The player base is tiny. Due to the above issues, and the fact that the game came with 1v1, FFA, TDM, CTF, and nothing new, next to no new players got into the game. Quake DM is a niche now anyway in the face of CS/BF2/CoD and so on, and to release such an unpolished game was MP suicide imo. The player base was always going to be small compared to the big 'real' shooters, but it didnt have to be as pathetic as it was a month ago, I dont know how it is now, ive stopped playing since it was easier to find an RA3 game then it was a Q4 game. While some may say ppl are just whiney, others say there are standards that should be attainable on a AAA title as Q4 should have been. /shrug
Will or has the patch fixed these issues, honestly with the new dude id has (Syncherror?) they probably will, the guy is doing a great PR job for id and is honestly working with and in touch with the community, so n1 id, theres a reason your one of the only companies I buy software from.
However for me its probably to little to late, I will wait for Quake Wars, or if RA4 gets big get into that again, but otherwise there are other games out there that are infinitly easier to get into that have a thriving player base.
