I liked Terrains but I always found it strange how you build on it, the terrain would often be uneven and it would just be a bit awkward. I preferred interiors but now that shaders are out I never want to go back. People may think shaders just makes Blockland look pretty but it does more, it fixed the glowing textures in the night time which was really something that bothering me, it also added a day and night cycle for games.
Terrain made BLs code complex and now bricks are 90% faster, I swear the Golden Gate Bridge loads faster in V21 then V20 and Badspot has confirmed that the non-shader version runs better on V21 than V20. Haven't you guys also noticed all of the recent updates with Blockland? The other updates we used to get we're scattered around throughout the year and now there's probably been on at least one update each month after V21.
