One thing to be mindful of is changes between different maps. I do a lot of that on my servers, and it is not always welcomed. Newer players seem not to mind, and instead enjoy the variety. But, some of the older players (which, ironically were the target of Alti+, to get them interested in returning to the game) complain that it is too difficult to get used to new physics. For example, on ball_whl, the two biggest gripes are the jagged walls and the lack of ball gravity. The walls issue doesn't affect your designs (I just think you don't bounce pass off the out-of-bounds line in soccer), but the gravity does.
If, in Altitude 1.1, some maps have ball gravity and some don't, you may hear complaints about how playing that map ruins a player's accuracy on other maps. I certainly do hear that. 4v4 soccer may not need such a large map, and so you may want to play with standard vs no ball gravity a little to see how it plays. I don't personally have a problem switching back and forth, but maybe I am just not good enough and finely tuned to the exact physics of Altitude for it to matter. My point here is simply to weigh the pros and cons making this variable across maps. In an earlier post, you stressed that things like viewable area, plane scale, health, etc. are likely to be consistent across Altitude 1.1 (and I think that will make a lot of people happy). This is the one place, ball gravity, where you appear to be considering a variable setting. So, I just thought your decision on this point might benefit from my experience.
I do wish ball_whl got more playing time, It is large, but the jagged walls do force game play into the field, it has no ball gravity so the whole map is open, you can't dunk so that increases passing and the role of a goalie, there are in-map spawn zones such that you spawn at the one closest one to where you died, and the spawn health changes based on how many players are on the map to keep it competitive and fun from 3v3 up to 7v7.
When the Altitude 1.1 servers start up, I will probably shutdown Football+ (EU) to lower the number of "other" servers new players might see, it doesn't get used a lot anyway, and it costs me ~$9/month.
Speaking of ball_whl, goodbye old friend
Thanks for all your work on Altitude in general, and on 1.1. I look forward to the new maps and game play. One benefit of 4v4 which hasn't been discussed enough is that sometimes (not as often as we would like) there are too many players waiting on Ladder. Smaller teams would mean there are times we might get as many as 4 competitive games going at once, and wouldn't that be nice. If we could eventually develop some
serverRequestPlayerChangeServer logic to rotate the players around so everyone gets a chance to play everyone else, that would be nice.
