I have a good idea of how the gameplay is going to be laid out for my next game, but I need some references from some well-polished indie PC games for inspiration. This game in particular is going to be like Advance Wars (a turn-based strategy for GBA) and I liked the overall look and feel of the visuals. However, I find it hard to make graphics using nothing but small pixel sprites look good in large resolutions. I will stick to 640x480, or possibly go as low as 320x240.

Really? I run my project in 1024x768 resolution usually, with 32x32 map tiles, 32x64 map sprites, and 64x128 battle sprites and it looks great. I don't really like it much when I can make out individual pixels of a character in a game, it's kind of a turn-off of sorts. [lol]

Come on, Ninja <3 Pirate was amazing at 320x240.
