Scene It? Bright Lights! Big Screen!

The description says "Complete 15 games in Classic or Fast Fire". I had a little problem with this one. I had completed about 20 classic short games and no achievement. It may have been gliching on me, so I went ahead and did 15 classic LONG games and then achievement unlocked for me. Hopefully this helps anyone who is having the same issues I did.

A couple of suggestions for the 100% out there.
1. Shoot for this and the "Complete a game with each avatar" one at the same time. I was having some gliching on the avatar one too. I had to play through classic long games for this one as well.

2. This can also be coupled with the "get and use star power twice in one game". I hated this achievement. I could never get a total of 2 stars after round one and 2 stars after round 2 to save my life in a short game. Only once I started playing long games (20 short games later) was I able to get a total of 4 stars in one game.

In my experience with this game play 10, 15 and different avatar achievements have to be done in one in one sitting.

Yesterday , and on and off during the week, I have been playing Fast Fire while keeping track of my avatar and no achievement. So today I decided I would start with the first avatar and work my way through. On my tenth game during this session achievement unlocked.

I believe this is also the case with the answer 100 questions achievement because I got the Best Picture achievement before I got any of the 100 correct answer achievemens.

(I pretty much copied and mildly edited this from my "avatar" solution - same concept, this achievement popped two games later so it's definitely working. YAY! ...and now hopefully the "100 question" cheevos will start popping. Fingers crossed!!!)

OK after much trial and error and probably over 40 or 50 games, easily and finally having it pop (during a Fast Fire game) I think the key is that it doesn't matter which mode you play (Long or Fast Fire) as long as they are all in the SAME mode. I don't think short mode counts unless my game is just glitchy - which I haven't discounted that yet.

Also, since I'm having trouble with some of my other "accumulative" achievements popping (but noticing that I had my 5 and 10 game achievements from a long time ago), I decided to move my profile BACK from my memory disk and onto my hard drive and also to try the trick of manually choosing my profile from the character screen at the beginning of EACH game.

I ran through each game like this on short game and nothing happened so I began runnig through each game on Fast Fire like this and I got this achievement about 1/2 way through.

I am hoping to start popping some of my 100 question achievements and my 15 game achievement soon (and frankly I'm afraid to turn my xbox off until I do as I have noticed that this game doesn't want to save my data and I don't want to chance it.) if I can stand it long enough and they start popping, I will update this solution in those achievement categories as well. Please do let me know if this helps you, especially if yours has been as glitchy as mine, and especially because if, for some reason I have to stop playing, I don't know if I have the wherewithal to start playing it again from scratch one more time so I'm curious if this helps anyone else start "accumulating" answers again. Hopefully this will work for those of us with buggy games. :)
