I think there is a lot to consider and probably why no one wants to respond. . .
I would weigh these things in order of importance
Light- How much natural light does this room have? Are there lots of windows, or is the room only partially enclosed etc?
Here is what most people don’t tell you about projectors. . .they are all about contrast. The darkest black your projector will make is completely dependent on the room light. Without a good black level, the picture will be washed out and hard to see, especially when viewing “dark” content (thin Spiderman, Lord of the Rings, etc) You can partially, (I stress that word) overcome this by getting a brighter projector, but that adds up quick in initial purchase and in maintenance on the bulb(s) (Some high brightness units use 2!)
Room Size- Bigger rooms can dictate bigger screens, and unless you have $100k to spend on a Panasonic 103” Plasma, projectors are the way to get more size. I say this is #2 as if you can’t see it (#1) it doesn’t matter how big it is.
Room Layout- Is this a partial gameroom? If you are sitting 10 feet back, and you have a 100” screen, your projector may be as far back as 14-15 feet. Will there be traffic in the light path of the projector behind the seating area that could affect this? Nothing worse than shadows on your screen eveytime your kids switch Fooseball positions. If you have higher ceilings this could be a non issue.
Damage- A fixed projection screen hanging on a wall has a gain coating on it that reflects the picture. This coating can be damaged leaving hot or dull spots. These are also bad places for kids to color, and large, white, framed “canvases” can be tempting. Are you tweens at the stage that this should not be an issue? Again you can do a manual or electric drop down screen, but nobody likes getting up to pull down the screen, and the electric ones get spendy. Also, if you want to recess the case to improve the look, you have a 50/50 shot that your ceiling joists are running perpindicular to the screen which can cause major issues in restructuring to make that happen.
I love projectors in the right environment, as I think they offer best bang for the buck in screen per inch. But many times they can be a bad investment.
Email me your room layout and light conditions, and I will post here with a gratis recommendation. “Giver’s Gain” and all :)
