---TCS Settings as part of the tune as it was in GT4 and GT5P
I really like the ability to have a different TCS level on different cars. Very low on some, 0 on others and a bit higher on others. Especially those high HP RWD beast that B-Spec Bob is trying to drive. He really needs some TCS on those. GT4 had this setting as well as ASM that could be adjusted as part of each of the 3 tunes but it seems to be gone in GT5.
---Prize money and EXP for online races both public and private.
There are so many cars in GT5 that we would all like to have and money is hard to come by. Would be nice is we could get some decent prize money in MP races.
---Invite to race/lounge feature.
It is difficult at present to let your friends know that you have a race lobby open or are in one. In Forza there is a very simple method to invite a friend to join you in a race. We need something like this in GT 5.
---More options in setting restrictions in race lobbies.
The recent addition of HP and weight restriction is a step in the right direction. We need more like drivetrain, Region, Make, Model and so on.
---Option to run a series of races in multiplayer mode.
It would be really nice to be able to pick 2 or 3 or more tracks then be able to set the number of laps on each track and have the race run as a series with an optional pause in between each race. Scroing here should be done as it is in championship events with points awarded in each race of the series to determine the overall winner.
---Nascar rules option in MP lobbies.
It would be very cool if we could activate the Nascar yellow flags into online races when desired.
---Ability to save a tune, perferrably with a name of our choosing or at least the 3 tune option that we had in GT4.
Many cars need to be tweaked a bit to run on different tracks especially when switching between sport tires and race tires. This is to difficult to remember and many of the cars are too expensive to buy two or three for the different setups. We need some way to save the tunes and as mentioned before this needs to include the TCS and ASM settings.
---Brakes.. Where did they go?
I see no options to upgrade brakes nor any options to set them in your tuning area. Are we only able to do this using the in race adjustments now? Do they stay with the car or is it global?
---Online events.
I think it would be really interesting if we could run some of the events that are in career mode in our private lobbies. Prize money would be the same as in career mode and 1 or more friends could get together and run the event in the lobby. AI drivers to fill in to make up for any empty slots.
---Career mode XP based on difficulty of race like A-Spec points were in GT4
For me the game would be a great deal more fun if we had an incentive to run a weaker car in the career mode events. For example if I were to enter a stock MX-5 into an event and win I should get more XP than if I won that same event with an LM race car.
--- Rally race options in online lobbies
I never really cared much for rally races but I must admit that I enjoyed the first rally challenge in the special events section. I would like to be able to setup events like this with my friends to race in the private lobby. I think this could be a lot of fun. And of course need prize money.
---Leaderboards and stats
We need leaderboards, lots of leaderboards. Need boards for totally stock cars like the time trails in GT5P and leaderboards for tuned cars. Need a way to track stats, wins, loses, races ran, miles driven and so on. I know leaderboards are coming just want to mention that there an not be to many leaderboards. The more the merrier.
